What rhymes with electromagnet?
Ferromagnet
Do ferromagnetic materials magnetize?
You can magnetize them by placing them near the magnetic field of a metal, this magnetizes them Another way to magnetize a ferromagnet it to wrap a insulated live wire around it, letting each end of the wire touch a + or - side of a bettery. This produces an electromagnet, and it can be turned on or off.
Describe how to distinguish a paramagnet from a ferromagnet by m versus h curves?
A ferromagnet has a steep gradient B /H curve with very noticeable hysteresis. A paramagnet has a shallow curve with almost no hysteresis.
Of a ferromagnet an electromagnet a temporary magnet or a permanent magnet which is easy to create but loses its magnetism easily?
The temporary magnet becomes a magnet in a strong magnetic field, but its magnetic properties will disappear when that field is taken away. The ferromagnet and the permanent magnet are essentially the same thing. The electromagnet isn't that easy to make compared to the temporary magnet. Let's conduct an esperiment. If we take a bar magnet and pick up a paperclip with it, we can use the paperclip on the end of the magnet to pick up another paperclip. The second paperclip we are picking up only needs to touch the first paperclip; it does not have to touch the magnet itself. When the magnet is taken away, the paperclips no longer exhibit magnetic properties. They were acting as temporary magnets, and the simple and easy removal of the magnet cause them to lose their magnetism.
Which is better a permanent magnet or an electromagnet?
electromagnet
Strong temporary magnet formed when a current is passed through a coil of wire?
