• The units for magnetic field are the tesla.
• Motors are devices that make use of electrical energy and loops of wire that generate a magnetic force, putting torque on a shaft.
• There is a strong relationship between the movement of charge and the creation of a magnetic field.
• The magnetic field can cause a deflection on a galvanometer but only when the magnet is moving.
• Inductance involves the generation of an emf by changing the current of a nearby device affecting another device.
• Electromagnetic waves involve a wide range of frequencies, indicating a substantive similarity between electricity and magnetism.
• All electromagnetic waves travel at the speed of light.
