JIPMER 2012 · Physics · Magnetic Effects of Current

A magnetic field exerts no force on

A magnetic field exerts no force on

Options

  1. Aa magnet
  2. Ban unmagnetised iron bar
  3. Ca moving charge
  4. Dstationary charge

Correct answer

D. stationary charge

Step-by-step solution

From F=qBv,F=0F=q B v, \quad F=0, when v=0v=0 i.e., a stationary charge experiences no force in a magnetic field.
