Dropping or heating a magnet will not weaken it because the domains will stay in alignment?
False
How does magnetic material become a magnet?
Placing the material in a strong magnetic field will align its' domains. You can swipe a metal tool on a magnet and make it a magnet.
Why will dropping an iron magnet on a hard floor make it weaker?
In case of iron there are domains which have been aligned facing one particular direction thereby making it as N-S magnet. As it is dropped then the alignment may get disturbed and so it makes the magnet weaker. Suppose we heat it then misalignment becomes enormous and so it would almost loose the magnetism
How voltage is induced in a permanent magnet pickup coil as the reluctor approaches alignment with the pickup coil.?
The Hall effect.
Why dousn't a magnet move to the North Pole?
It is impossible currently to create a magnet with only one pole, or magnetic monopole. This is because a magnet arises from the magnetic directional alignment of the material, so cutting a bar magnet in half will simply cause the two pieces to become their own bar magnets, both pointing the same way as the original.
What is hot alignment and cold alignment in turbines?
alignment in turbines use magnet dialgades and make mesuring 00.o1 micrones
Dropping or heating a magnet will not weaken it because the domains will stay in alignment?
False
How can a magnet become demagnetized?
A magnet can become demagnetized by exposure to high temperatures, strong magnetic fields, or physical impacts that disrupt the alignment of its magnetic domains. These factors can cause the magnetic domains to lose alignment, weakening or eliminating the magnet's magnetic field.
What is a temporary magnet caused by an electrical current?
A Electro Magnet, caused in theory by the alignment of the particles in the material duo to the current passing through it.
What do you understand by demagnetization?
De-magnetism is when a magnet is no longer a magnet. For example, when a magnet becomes heated it loses its magnetism. This is because the alignment of domains (groups of atoms) is disrupted. This is due to the expansion of the domains; the energy to expand is provided from the heat. During the expansion, the domains require more space therefore disrupting the alignment. This causes a magnet to become weaker and weaker to the point where it is no longer a magnet.... Hope this helps! :)

Explain in brief the properties of magnet?
A magnet has both a South pole and a North pole. The magnetic properties of a magnet come from the alignment of electrons inside of the magnet. The North pole of a magnet will repel another North pole, but attract a South pole, and vice versa.

What is one way that a magnet's domain could become unaligned?
heat
What might happen if you drop a permanent magnet or strike it hard?
A permanent magnet may become unmagnetized because a shock it will have.
Why does a magnet loses its magnetism when it is strongly heated or hammered?
A magnet is an alignment of particles in a solid. You can imagine a magnet as a bunch of tiny magnets that are all pointing in the same direction. When they point in the same direction, the little parts add up, and the magnet works like you'd expect. When you heat or hammer a magnet, the little magnetic parts can get jostled and unaligned. When that alignment is disturbed, they no longer point in the same direction and may even cancel other magnetic parts out, weakening and eventualy destroying the magnetism.
