What else can I help you with?
An electromagnet becomes stronger when?
You run more copperwire around the coil, or induce more curent in the wire.
How can you make an electromagnet stronger?
More wire wrappings, Larger Iron core, more and stronger electricity, etc
Would a powerfull electromagnet lift a needle out of a haystack?
Only if the needle was made of iron or copper
Why electromagnet is different from a permanent magnet because an electromagnet what?
Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
Why are electromagnets used in generators?
My only guess is that ,,, because electromagnets are more stronger and powerful than the ordinary magnets. Moreover they provide continuous magnetic field required for the generator. the generator in your car will have an electromagnet in the field the field will set the charge rate new cars have an alternator the field is the electromagnet in the rotor older cars have a true generator where the field is in the stator
Can an electromagnet be made stronger and stronger without stopping?
yes it can
How can you make an electromagnet's pulling force stronger?
An electromagnet's pulling force can be made stronger by introducing iron core in it.It increases the magnetic pull.
Does using a stronger battery create a stronger electromagnet?
Using a stronger battery can increase the current flowing through the electromagnet, which in turn can increase the strength of the magnetic field produced by the electromagnet. So, a stronger battery can result in a stronger electromagnet.
Is an electromagnet made of a coiled wire and a metal bolt stronger than one made with a wire alone?
Yes. An Iron core electromagnet has a stronger magnetic field then a coil. The magnetic flux is condensed and travels through the iron core with little resistance, while air provides much greater resistance.
What is a stronger electromagnet?
Neodymium
What are three ways to make an electromagnetic stronger?
Increase the number of coils in the electromagnet. Use a stronger magnetic material in the core of the electromagnet. Increase the current flowing through the wire winding of the electromagnet.
Which is not a way to make an electromagnet stronger?
To chew on it.
Which is a stronger electromagnet- a nail or a bolt?
Bolt
Why does the strength of the electromagnet increase from the coils?
The strength of an electromagnet increases when current flows through the coils because the current generates a magnetic field around the coils. This magnetic field interacts with the metal core of the electromagnet, aligning the domains within the core and creating a stronger magnetic field. More current leads to a stronger magnetic field, resulting in a more powerful electromagnet.
How an electromagnet be made stronger?
An electromagnet can be made stronger by: - A bigger iron rod. - A bigger battery/more batteries - More coils around the iron rod. - A bigger magnet. - Increase the current flowing through the coil. - Put in a soft iron core.
What are the 3 ways to make an electromagnet stronger?
To make an electromagnet stronger, you can increase the current flowing through the coil, increase the number of turns in the coil, or use a material with high magnetic permeability as the core of the electromagnet, such as iron.
Is an electromagnet made of a coiled wire and a metal bolt is stronger than one made with a wire alone?
Yes. An Iron core electromagnet has a stronger magnetic field then a coil. The magnetic flux is condensed and travels through the iron core with little resistance, while air provides much greater resistance.
