A wire of 80 cm long is bent into a square loop. The wire carries a current of 2.0 A. Then, the loop is immersed in a uniform external magnetic field of magnitude 0.4 T, directed orthogonal to the loop. Determine the magnitude of the magnetic force on each side of the loop due to the uniform external magnetic field. Then, if the plane of the loop is rotated to be parallel to the direction of the uniform external magnetic field, determine the magnitude of the torque on the loop.​

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
