A magnet can make something move by exerting a force on certain materials like iron, nickel, and cobalt. When these materials are attracted to the magnet, they can move towards or away from it depending on the orientation of the magnet. This movement is caused by the magnetic field surrounding the magnet interacting with the magnetic properties of the material.
To make a magnet float using another magnet, you can use the principle of magnetic repulsion. By placing two magnets with like poles facing each other, the repelling force between them can create a levitating effect, causing one magnet to float above the other.
When a magnet is brought near a light bulb, the magnetic field interacts with the electric current flowing through the filament, causing a force to be exerted on the filament. This force can make the filament move or vibrate, resulting in changes in the brightness or flickering of the light bulb.
In general, magnets are brittle and will break before they bend. And yes, refrigerator magnets bend, but in them the magnetic material is powdered. But if we took a bar magnet and bent it, we'd have a horseshoe magnet. It's not quite that simple to make a horseshoe magnet, but it isn't too tough, either.
You cannot make a magnet stick directly to aluminum because aluminum is not magnetic. However, you can make a magnet stick to aluminum by placing a magnetic material, such as iron, in between the magnet and the aluminum surface.
by keeping another magnet or attractive force
You can’t.
Yes. Placing a rotating magnet below it can generate a magnetic field that creates a spin in the suspended magnet. If the magnet is mounted on a low-friction axis, bringing an opposite pole toward one side of the magnet, then removing it, will add force to spin it for awhile.
You can supercharge a magnet by coiling a metal wire around a magnet then hooking both ends of the wire to a battery. Make sure the wire can conduct electricity and the more coils around the magnet, the better.
You can’t that’s impossible

Wrap copper wire around a nail, then attach the ends of the wire to a D battery with tape to make an electromagnet.

Magnets can make electrons accelerate and change position through force;f= evB = -ev.Bcos(vB) + evxBsin(vB).
The poles of an electromagnet can change depend inf on the current supplied.
