PaperClip Motor
... GOAL: Today’s activity is to build and operate a paper clip motor. Motors are a main component in mechanical systems, which are often used due to their simplicity, efficiency and ease of integration. Today, we can see motors in hybrid cars, pencil sharpeners and toys. While motors have only been aro ...

... σ = Ne qe µe Since the product Ne qe is effectively independent of temperature, the influence of variables such as temperature on the conductivity of a conductor can be understood in terms of its effect on electron mobility. Simply stated, since the mobility decreases with increasing temperature, el ...

Unit 5 – Electricity and Magnetism
... An electric motor uses an electric current to turn an axle that can then turn something else (such as the blades of a fan). An electric motor converts electrical energy into mechanical energy. Like a galvanometer, an electric motor has loops of wire suspended between the poles of a magnet. The loops ...
