MCQ
A paramagnet magnet behaves like a solenoid because both contain currents in the form of:
  • A
    Circles.
  • B
    Parabola.
  • C
    Straight line.
  • D
    Ellipse.

Answer

  1. Circles.

Explanation:

A paramagnet magnet behaves like a solenoid because both contain currents in the form of circle. The magnetic field is generated by the circular motion of the electron inside the atom.
