Magnet A exerts an attractive magnetic force of $5\text{ N}$ on Magnet B. What is the magnitude of the force exerted by Magnet B on Magnet A?
  1. $0\text{ N}$
  2. $2.5\text{ N}$
  3. $5\text{ N}$
  4. $10\text{ N}$

Solution

Magnetic interaction forces are mutual and equal in magnitude; Magnet B exerts an equal $5\text{ N}$ force on Magnet A in the opposite direction.
