Question

You should have observed in Activity 26.5.2 that a permanent magnet can exert forces on moving charges or currents.

(a) If a magnet exerts a force on a moving charge would the magnet experience any forces? Explain
(b) In the case of the gravitational or electrostatic interaction between two objects, each object has a common property such as mass in the case of gravitational interaction or excess charge in the case of the electrostatic interaction. A permanent magnet and a moving electron seem very different. Can you think of any way that they might have a common property? Explain.

Explanation / Answer

(a)Yes because moving charges produces magnetic fields around it. So moving charge can behaves like a magnetic dipole So magnet experience a force due to moving charge (b) Since both can behaves like a magnet Attracting of repel property common for both
