so for this question, i have an inclined plane with a coil of wire wrapped longitudinally around a cylinder N turns. the plane of the coil is parallel to the inclined plane with a uniform magnetic field they want me to find the least amount of current necessary to prevent the cylinder from rolling down the plane. I am given mass of the cylinder, magnitude of the magnetic field, length of the L portion of the cylinder, & N number of turns. I am not sure where to start, i have this equation, torque=Ntorque'=NiABsin(phi) where A equals area but I am only give the L part of the cylinder.
i need to have this done by tonight if anyone can help
