- Solution of problems
- A magnet attracts small pieces of iron.
- Like poles of two magnets repel while unlike poles of two magnets repel each other.
- A freely suspended magnet always points in the north-south direction.
- The magnetism of a magnet concentrated in its poles.
- The two poles of a magnet cannot be separated from each other. If a magnet is broken into two pieces, then two new magnets are obtained.
- There is a magnetic field around a magnet. A test magnet or a current-carrying conductor experiences force in a magnetic field.
- A compass needle is often used to investigate a magnetic field.
- It can also be used to detect current in a conductor.
- The static charge produces electrostatic effects.
- While a moving charge that is current produces both electric and
- The magnetic field is strong near the conductor and becomes weaker and weaker as we move away from the conductor.
- The magnetic field exists as long as the current is flowing through the conductor.
- The magnetic lines of force are circular around the conductor.
Magnetic Field of a straight current-carrying wire:
“A magnetic field produced around a conductor due to flow of electric current in it is known as the magnetic field due to current”.
