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.

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.
What is a stronger electromagnet?
Neodymium
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.
Why does the strength of the electromagnet increase from the coils?
The electromagnet is made stronger in proportion to the current given. Refer to the link provided for more information.AnswerWhen current passes through the coil of wire surrounding the core of an electromagnet, it acts to align the magnetic domains within that core. Once all the domains have been aligned, the electromagnet has reached 'saturation' and is as strong as it can get. So the strength of an electromagnet is NOT proportional to its magnetising current.
What is a stronger electromagnet - a nail or a bolt?
Bolt
Which is a stronger electromagnet- a nail or a bolt?
Bolt
Which is not a way to make an electromagnet stronger?
To chew on it.
Which has a stronger magnetic field a solenoid or a electromagnet?
A solenoid is an electromagnet An electromagnet is a solenoid with an iron core
Is an electromagnet made of a coiled wire and a metal bolt stronger than one made with 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.
