The current in the closed coil is received in the magnetic fieldAmberiThe effect of the ampere force causes the coil to rotate, that is, the ampere force produces the torque that causes the coil to rotate. This torque generated by the ampere force is called the magnetic torque.The direction is the same as that of the unit positive normal vector 'cross product' magnetic field intensity vector B in the coil plane.
Chinese name
Magnetic moment
Calculation formula
M=NBISsin θ (θ is the angle between magnetic moment and magnetic induction line)
