What else can I help you with?
Can Permanent magnets be turned on and off?
Electromagnet which uses electric current can be turned on and off.
What can you use your statemennt for?
Permanent magnets can be turned off.
How are electro magnets different from other magnets?
Electromagnets use electricity to create a magnetic field, which can be turned on and off. They are typically stronger than permanent magnets. In contrast, permanent magnets, like those made of iron or nickel, are always magnetic without the need for an external power source.
What are electromagents?
Magnets that are turned on by passing an electric current through them, and turned off by not allowing an electric current through them.
How are electromagnets different from magnets?
You can turn electromagnets on and off.
Is electromagnets are natural magnets?
The magnetism of an electromagnet is natural (it comes out of the laws of physics), but the magnetism disappears when the electricity is turned off - it is not a permanent magnetism.
How are magnets used in electromagnets?
An electromagnet makes a great door lock. The steel in the door will stay put until the electromagnet is turned off.
How magnets are used in locks?
An electromagnet makes a great door lock. The steel in the door will stay put until the electromagnet is turned off.
What are the differences between electromagnets and permanent magnets, and how do electromagnets differ from permanent magnets?
Electromagnets and permanent magnets differ in how they are created and their magnetic properties. Electromagnets are temporary magnets created by passing an electric current through a coil of wire, while permanent magnets are naturally occurring magnets with a fixed magnetic field. Electromagnets can be turned on and off by controlling the electric current, while permanent magnets always have a magnetic field.
What are the differences between electromagnets and permanent magnets, and how do they function differently?
Electromagnets are temporary magnets created by passing an electric current through a coil of wire, while permanent magnets are naturally occurring magnets that retain their magnetism without an external power source. Electromagnets can be turned on and off by controlling the electric current, while permanent magnets always have a magnetic field.
What do magnets attract that electromagnets do not?
Magnets attract magnetic materials like iron, nickel, and cobalt. Electromagnets, on the other hand, can attract or repel any material that responds to a magnetic field, as they can be turned on/off by controlling the electric current flowing through them.
What kind of metals are attracted to magnets or can be made into magnets?
Metals that are attracted by magnets or that can be turned into magnets are as follows: 1-iron 2-cobalt 3-nickel 4-steel (a compound not an element)
