Question
On reversing the direction of current in a wire the magnetic field produced by it:
- Reverses direction
- Increase in strength
- Decrease in strength
- Remains unchanged in strength and direction
Hint:
On reversing the direction of current in a wire, the magnetic field produced by it reverses direction.
The correct answer is: Reverses direction
On reversing the direction of current in a wire, the magnetic field produced by it reverses direction.
- The direction of the magnetic field is dependent on the direction of the current.
- The magnetic field is circular when the current-carrying conductor is passed straight.
- When the current flow is reversed, the the polarity of the faces of the wire also reverses.direction of the electromagnetic field gets reversed.
