The electric power is measured the same as in any other electric circuit, in watts. You calculate this by multiplying the current (in amps) by the potential difference (in volts) across the circuit. So:
P = I V
If you meant how do we measure the strength of the magnetic field generated, there are two different vector fields that may be called "magnetic field". These are the H-field and the B-field.
The H-field may also be called the "magnetic field intensity", the "magnetic field strength", the "auxiliary magnetic field" or the "magnetising field". It is measured in amps per metre.
The B-field may also be called the "magnetic flux density", the "magnetic induction", or the "magnetic field". It is measured in teslas.
ampere turns! I just took a test on it. ampere turns! I just took a test on it.
it appears that the answer is Newtons.
with gas tubes and a gauge thingy
The copper, technically, wouldn't increase it's power but rather extend the magnetic field of the magnet.
A natural magnet is permanent - an electromagnet loses its power when it's switched off.
The bar magnet and the electromagnet act identical. The difference being a electromagnet is a coil of wire that has a power source connect to both ends, this energizes the coil with an electromagnetic field.
After liquid helium is cut off, the temperature could rise up and reach temperature. Under these circumstances, the magnet can demagnetise
A paperclip attracts a magnet ,a magnet attracts a paperclip.
Electric Power
No.If you break the magnet, it is still a useful magnet.
Some power stations do work with a wire and magnet but some others don't.
With magnets
It is a permanent magnet. Electromagnets(as the name suggests) requires an electric source to become a magnet, when the power source is turned off it will not function as a magnet.
That's called a permanent magnet.
The copper, technically, wouldn't increase it's power but rather extend the magnetic field of the magnet.
because it is
by the power of the magnet.
When we pour water onto a magnet it loses a little bit of magnetic power.
Yes, a magnet looses it's power even when it is hammered.
A magnet can lose its magnetism if exposed to high temperatures. If heated above the point called the Curie temperature, a magnet will lose its magnetism.
