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. WebJan 13, 2024 · This causes continual rotation of the loop. In a uniform magnetic field, a current-carrying loop of wire, such as a loop in a motor, experiences both forces and torques on the loop. Figure 7.6.1 shows a rectangular loop of wire that carries a current I and has sides of lengths a and b. The loop is in a uniform magnetic field: →B = Bˆj. WebThe torque about this axis is: τ = F (a/2) + F (a/2) = Fa = IabB. ab is the area of the loop, so the torque is, in this case, τ = IAB. This is actually the maximum possible torque, when the field is in the plane of the loop. When the field is perpendicular to the loop the torque is zero. In general, the torque is given by: τ = IA × B biology cells worksheets free printable
