How do you know if there is magnetic torque

WebMay 4, 2024 · the torque is τ = p x B where p x B is the vector cross product (= the magnitude of p and B times the sine of the included angle ), and B is the magnetic field inside the solenoid. If you know the moment of inertia of the magnet, you can calculate the oscillation period of the magnet in the solenoid. WebMay 12, 2016 · I know that if a current was flowing through this ring, the torque exerted by a magnetic field would be given by I ( A ^ × B ^). Where I is the current flowing in the circuit, A is the area of the coil and B is the magnetic field. As I understand, a current is just a flow of charge, or in other words, changing charge.
