Question

Write any two methods of causing magnetic field

Answer 1

Answer:

• Magnetic force between two currents going in the same direction.
• Magnetic force between two currents going in opposite directions.
• Induced current in a wire.

Answer 2

Answer:

There are two basic ways which we can arrange for charge to be in motion and generate a useful magnetic field: We make a current flow through a wire, for example by connecting it to a battery. As we increase the current (amount of charge in motion) the field increases proportionally.
