You should have observed in Activity 26.5.2 that a permanent magnetcan exert forces on moving charges or currents.
(a) If a magnet exerts a force on a moving charge would the magnetexperience any forces? Explain
(b) In the case of the gravitational or electrostatic interactionbetween two objects, each object has a common property such as massin the case of gravitational interaction or excess charge in thecase of the electrostatic interaction. A permanent magnet and amoving electron seem very different. Can you think of any way thatthey might have a common property? Explain.
