Frequently Asked Questions
What is a magnetic field?
A magnetic field is the region around a magnet or a current-carrying conductor where a magnetic force can be detected. It is a vector quantity, having both magnitude and direction.
What are magnetic field lines?
Magnetic field lines are imaginary curved lines used to represent a magnetic field. Outside a magnet they run from the north pole to the south pole, and their direction at any point is the direction a compass north pole would point.
Why do two magnetic field lines never intersect?
If two field lines crossed, a compass placed at that point would have to point in two different directions at once, which is impossible. So magnetic field lines never intersect.
How do you find the direction of the magnetic field around a straight current-carrying wire?
By the right-hand thumb rule: point the right thumb in the direction of the current, and the way the fingers curl gives the direction of the circular magnetic field lines around the wire.
