Question
The attracting power of a magnet is
- Evenly distributed along its length
- Maximum at its center
- Maximum at its poles
- Minimum at its poles
Hint:
The attracting power of a magnet is maximum at its pole.
The correct answer is: Maximum at its poles
- The strength of the magnetic field depends on the current supplied through the coil and wire.
- The magnet has high attracting power on its poles.
- That's why the lines of a concentric circle of magnetic field start and end at the poles.
- The centers of the concentric circles that make up the magnetic field lines caused by a straight wire carrying a current are located on the wire. To determine the direction of the magnetic field, magnetic field lines are used.
