What is magnetic field lines Class 10
Magnetic field lines are imaginary lines around the magnet. The magnitude of a field is indicated by its line's density. Near the South and North Pole of a magnet, the magnetic field is stronger and will get weaker when it moves away from the poles.
Which electromagnetic is the strongest
The strongest continuous magnetic fields on Earth have been produced by Bitter magnets.
What is the direction of magnetic field
The direction of magnetic field lines is defined to be the direction in which the north end of a compass needle points. The direction of magnetic field is taken by convention that the field lines emerge from North pole and merge at the South pole.
What is the property of magnetic field lines
Following are the properties of magnetic field lines: They form closed loops. They never intersect each other. The magnetic field lines are crowded near the pole where the field is strong and spread apart from each other where the field is weak.
What is right hand thumb rule Class 10
Thumb rules state that if the thumb of the right-hand points along the direction of the current, then the remaining curled, fingers of the same hand give the direction of the magnetic field due to the current.
What is the right hand thumb rule
Right Hand Thumb Rule: If a current carrying conductor is imagined to be held in your right hand such that the thumb points along the direction of current, then the direction of the wrapped fingers will give the direction of magnetic field lines.
What is the weakest magnet
There are five main types of permanent magnet material; these are, in order of strength from strongest to weakest, neodymium, samarium cobalt, alnico, ferrite, and flexible rubber.
What is the fastest electromagnetic
Light wave – light wave is an electromagnetic wave which can travel in vacuum and all electromagnetic radiation travels at the same speed which is about $3 \times {10^8}m/\sec $ through a vacuum. We call this the "speed of light"; Nothing can move faster than the speed of light.
What is the left hand rule for magnetic field
Field from north to south. So your finger is pointing to the south pole. Your second finger represents the direction of the electric.
What is the left hand rule in physics
The direction of this force can be determined using Fleming's left-hand rule. By placing the middle finger in the direction of the current, the index finger in the direction of the magnetic field, and the thumb in the direction of the force, you can determine the direction in which the wire will move.
What are the 4 properties of magnetic field lines Class 10
Magnetic field lines appear to emerge or start from the north pole and merge or terminate at the south pole. Inside the magnet, the direction of the magnetic field lines is from the south pole to the north pole. Magnetic field lines never intersect with each other. Magnetic field lines form a closed-loop.
What are the two properties of magnetic field lines Class 10
Two properties of magnetic field lines are: They never cross one another. They flow from the south pole to the north pole within the magnet and north pole to south pole outside the magnet.
What is left hand thumb rule in simple words
If the forefinger indicates the direction of the magnetic field and the middle finger, the direction of the current, then the thumb will indicate the direction of the force which results in the motion of the conductor.
What is right and left hand thumb rule
This rule states "Hold out the right hand with the first finger, second finger and thumb at right angles to each other. If forefinger represents the direction of the line of force, the thumb points in the direction of motion or applied force, then second finger points in the direction of the induced current.
What is left hand thumb rule
Fleming's Left Hand Rule states that if we arrange our thumb, forefinger and middle finger of the left hand perpendicular to each other, then the thumb points towards the direction of the magnetic force, the forefinger points towards the direction of the magnetic field and the middle finger points towards the direction …
Which magnet is stronger than Earth
The hybrid magnet managed to produce a field measuring 45.22 Tesla (T), which is over a million times stronger than the planet's own. The record was set at the Steady High Magnetic Field Facility (SHMFF) in Hefei, China, using a magnet with a hybrid design that's been operating since 2016.
What is the hardest magnet in the world
neodymium-iron-boron magnet
A neodymium-iron-boron magnet is the strongest magnet in the world, with a strength of up to 34 tons. The neodymium-iron-boron magnetic field is so powerful that it emits a shrieking sound when turned on. However, it can only be turned on for a short time.
Is electromagnetism faster than light
Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum. We call this the "speed of light"; nothing can move faster than the speed of light.
What wave has the fastest speed
Light wave
Light wave – light wave is an electromagnetic wave which can travel in vacuum and all electromagnetic radiation travels at the same speed which is about $3 \times {10^8}m/\sec $ through a vacuum. We call this the "speed of light"; Nothing can move faster than the speed of light.
What is the left hand thumb rule
Fleming's Left Hand Rule states that if we arrange our thumb, forefinger and middle finger of the left-hand perpendicular to each other, then the thumb points towards the direction of the force experienced by the conductor, the forefinger points towards the direction of the magnetic field and the middle finger points …
How does the left hand rule work
The current is going in this direction. So the force is going up for b the current has changed direction. So you need to rotate your hand. Around.
What is left hand thumb rules
Fleming's Left-Hand Rule
If the forefinger points in the direction of magnetic field, the middle finger point in the direction of current, then the thumb will point in the direction of the force".
What is left hand thumb rule in short
Fleming's Left Hand Rule states that if we arrange our thumb, forefinger and middle finger of the left-hand perpendicular to each other, then the thumb points towards the direction of the force experienced by the conductor, the forefinger points towards the direction of the magnetic field and the middle finger points …
What are the 4 important properties of electric field lines
Properties of electric field linesThey start from a positive charge.These lines end on a negative charge.The movement of electric field lines is away from the positive electric charge.The movement of electric field lines is towards the negative electric charge.
What are the three characteristics of magnetic field lines Class 10
Magnetic field lines never intersect with each other. Magnetic field lines form a closed-loop. Field lines have both direction and magnitude at any point on the field. Therefore, magnetic field lines are represented by a vector.
