A permanent magnet may become unmagnetized because a shock it will have.
The main types of magnets areBar MagnetHorseshoe MagnetCylindrical MagnetBall-ended MagnetThese are the main types . There are many more types .
We might have a meter but we don't know how can we tell accept the magnet test
The word "could" implies a future possibility that might or might not happen.
An educated guess or prediction on what might happen
sometimes it is because you might not know what is going to happen.
Dropping a permanent magnet can cause the magnetic domains within the material to become misaligned, reducing its overall magnetic field strength. This process can demagnetize the magnet if it is subjected to a strong enough impact.
nothing would happen
There might be a Kiki Strike movie, but so far Kirsten Miller is not positive if it will actually happen.
When a permanent magnet is dropped, the impact could cause the magnetic domains within the magnet to become misaligned, leading to partial or total demagnetization. The force and shock from the drop can disrupt the alignment of the magnetic domains, causing the magnet to lose its magnetic properties.
To vary the speed of a permanent magnet synchronous motor, you need to vary the frequency of the AC power source. Of course, this also means you need to vary the voltage because the power factor is going to change, and you need to compensate for that or you might damage the motor.
nothing will happen dumbazz because it isnt magnetic
Apart from a lot of loud humming, the motor would not turn, it would take a lot of current and, if the circuit breaker did not trip to cut the supply of current, it would probably overheat or might even catch on fire.
It depends on the type of lamp and the strength of the magnet. An incandescent lamp works literally by running current through the filament to heat it. Parts of the bulb might be magnetic, so if the magnet were ridiculously powerful it might deform or break them. Fluorescent and Neon lamps use ionization, so although I haven't tried it, I'd bet a reasonably strong magnet might affect them. If you have an old CRT-based television or computer monitor you can see how this works by placing a magnet near it -- note, this can cause permanent effects to the picture quality, so either keep the magnet at a distance where the effect is minimal or use a CRT you don't care about. LED lamps are so small and well-constructed that I think they're more like incandescent lamps -- a really powerful magnet might damage them, but otherwise is unlikely to affect them.
Nothing "would happen". There are lots of things that might happen, depending on the exact circumstances.You would probably find it difficult to do this without their permission, though.
On your refrigerator.
no one really knows. but i have a theory. there could be a magnet in the triangle . because they say compasses don't work, and weird things happen to communication and radar. might be something else though
It might damage the floor, and it might damage the magnet.
