A 1.0 kg copper rod rests on two horizontal rails 1.0 m apart and carries a current
Question:
A 1.0 kg copper rod rests on two horizontal rails 1.0 m apart and carries a current of 50 A from one rail to the other. The coefficient of static friction between rod and rails is 0.60. What are the (a) Magnitude and
(b) Angle (relative to the vertical) of the smallest magnetic field that puts the rod on the verge of sliding?
Step by Step Answer:
a The magnetic force must push horizontally on the rod to overcome the force of friction but it can ...View the full answer

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. The video shows the practical implications of magnetic force around different objects.
