• Similar poles repel, unlike poles attract

• Show north-south direction

• Has north and south poles

Choose the correct statements based on the given diagram

• The magnetic field never cross each other

• The magnetic field lines begin from the north pole and end at the south pole.

• The magnetic field lines begin from the south pole and end at the north pole.

• The magnetic field lines are closer to one another when the magnetic firld are closer

A magnetic field between two like poles will produce a

• Repulsion lines

• Free from magnetic force

• neutral region

• Neutron region

What is electromagnet?

• A type of magnet made from a combination of steel, iron and cobalt.

• A type of magnet with temporarily magnetic effect.

• A type of magnet which produced when electric current is flow through it.
