... Magnets have the strongest force at the poles A free swinging magnet will point north with its north seeking pole-that end is marked with an N. Like electrical charges, opposite forces between magnetic poles attract, N-S, positive –negative Like poles repel: south repels south; north repels north Ma ...

... single loop or wire is such that the loop will behave like a magnet or compass needle and swing until it is perpendicular to a line running from the north magnetic pole to the south. The magnetic field about a current-carrying conductor can be visualized as encircling the conductor. The direction of ...

SUMMARY 1. Define motor and generator. A motor is a device
... A motor is a device which converts electrical energy to mechanical energy (or motion). A generator is a device which converts mechanical energy into electrical energy. 2. What does the term “magnetic field” describe? The region surrounding a magnet where magnetic effects can be detected. A compass n ...
