A mass is attached to a spring through which circulates an electric current. Will the mass move?
2. Relevant equations
F = I l [itex]\times[/itex] B ?
3. The attempt at a solution
A spring is geometrically equivalent to a solenoid. Therefore, the current would generate a magnetic field which goes through the spring. What I’m not sure of is whether this magnetic field exerts a force on the solenoid or not.
