Electricity - The Lesson Locker
... To visualize fields around electric charges, we draw a series of lines to indicate the direction of the field at various points. These lines are called electric field lines and we draw them so that they indicate the direction of the force that the field would apply to a positive test charge. ...

... 42*. A man doing his spring cleaning pulls a 150N vacuum cleaner across the floor at a constant velocity by exerting a force on it at an angle of 30 with the horizontal. If the required force is 35N, what is the kinetic coefficient of friction between floor and vacuum? 44* A crate is held at rest o ...

... flows, the coils produce a magnetic field. The iron nail is not necessary for an electromagnet, but it is used to enhance the magnetic field. A fluxgate magnetometer uses some of these same concepts, plus more. A fluxgate magnetometer measures an external magnetic field in any direction by determini ...

Electric Field Lines
... In physics, a ‘force’ field describes an area where objects experience a force-at-a-distance such as gravity, electrostatic force, or magnetism. In each case, the field is generated by a certain type of particle: • Gravity by a mass • Electrostatic by a charge • Magnetism by a moving charge Watch me ...
