Currents are thus induced in a bobbin of fine wire placed between the poles of the horseshoe magnet.
In magnetism, a piece of soft iron used to connect the poles of a horseshoe magnet, for the purpose of preventing loss of power.
Its field crossing the field of the horseshoe magnet, tends to turn until its turning force is balanced by the spiral springs.
It was as flat and cleancut as the inside surface of a horseshoe magnet.
To find whether a current can be generated with a horseshoe magnet and a coil of wire having an iron core.
If the ordinary bar or horseshoe magnet be carefully examined, one end will be found to be marked N.
The horseshoe magnet, H M; two sewing-needles that have never been near a magnet; iron filings.
In this simple machine the lines of force exist between the poles of a horseshoe magnet.
Two straight permanently magnetized bar magnets 1-1 are clamped together at their opposite ends so as to form a horseshoe magnet.
In Fig.4 M is a magnet bent into the form of a U, commonly called a horseshoe magnet.
