by simple moving of its needle,or by change the direction of needle.
If the refrigerator magnet can't hold a piece of paper against the refrigerator, it may be due to the forces of gravity overcoming the magnetic force produced by the magnet. The weight of the paper pulling it down is greater than the magnetic force trying to hold it up.
The magnetic forces from the North and South pole send magnetic forces around the earth, that's why on a magnet you cant stick North and North or South and South, They have the same magnetic force
i thin magnetic force cant work in air
beacause of magnetic force
No, magnets do not stick to silver because silver is not a magnetic material. Magnets are attracted to ferromagnetic materials like iron, nickel, and cobalt. Silver is a non-magnetic metal.
To weaken a magnet, you can heat it to a high temperature, subject it to mechanical shock, or expose it to a strong magnetic field in the opposite direction. These methods can disrupt the alignment of the magnetic domains within the material, reducing its overall magnetism.
A magnet finding glass, also known as a magnetic pickup tool, has a magnet on one end that can attract and pick up metallic objects like screws, nails, and small tools. When the magnet comes into contact with a metallic object, it creates a magnetic field that attracts and picks up the object, allowing you to retrieve it easily.
Materials like iron, nickel, and cobalt are the most effective at blocking magnetic force due to their ability to become magnetized and create an opposite magnetic field, which cancels out the incoming magnetic field. Other materials like copper and aluminum are weakly affected by magnetic fields and are considered non-magnetic.
The comon bar magnet has two poles, and the electromagnet can be turned on and off also the electromagnet uses electricity to create a magnetic field in the first place. so the difference is normal magnet cant be turned on and off but the electromagnet can. does that answer ur question?
you can hang as many paper clips as you want until the weight of the paper clips becomes more than the pulling force of the magnet
you cant put a signature on the samsung magnet
you cant ?i dont think Answer (Contrablue)If the nail is made of iron or steel (an alloy of iron with a bit of carbon and usually certain metals such as molybdenum or chromium), it can be magnetized by rubbing it against a magnet. That is the easy and cheap way to turn a nail into a magnet.A more expensive way is to use a machine that subjects the nail to a strong magnetic field. This can turn the nail into a reasonably strong magnet. However, most of us don't have access to such a machine.
