10.8   Torque

10.8   Torque

10.8   Torque. Torque is a turning or twisting action on a body about a rotation axis due to a force, . Magnitude of the torque is given by the product of the moment arm and the magnitude of the force. Torque is a vector. The SI unit of torque is the newton-meter (N · m).

Chapter 19

Chapter 19

Chapter 19. Magnetism. Magnets have two ends – poles – called north and south. Like poles repel; unlike poles attract. If you cut a magnet in half, you don’t get a north pole and a south pole – you get two smaller magnets. Types of Magnetic Materials.
