Electromagnet two is stronger than electromagnets one and three because it generally has a greater number of coil turns and a larger current flowing through its wire, resulting in a stronger magnetic field being produced. Additionally, the core material used in electromagnet two may be better suited for enhancing the magnetic field strength compared to the cores used in electromagnets one and three.
What else can I help you with?
Are electromagnets stronger or weaker than permanent magnets?
Electromagnets can be stronger than permanent magnets because the strength of an electromagnet can be adjusted by changing the amount of electric current flowing through its coil. On the other hand, permanent magnets have a fixed magnetic field strength determined by the material they are made from.
What are the advantages of electromagnets against normal magnets?
Electromagnets' magnetism can be manipulated. Electromagnets can be magnetised and demagnetised by passing electric current. Therefore they are used in motors- which works when the coil is magnetised by passing an electric current. It is also used for cranes.
Is an electromagnet stronger than a permanent magnet?
Not necessarily. The key difference between a permanent magnet and an electromagnet is the a permanent magnet does not change whereas an electromagnet's magnetic feild can be altered by varying the current through it. This means that electromagnets are more useful because they can be turned on or off, turned up or down or be put in 'reverse'.
Why is a crane in a steelworks fitted with a large electromagnet?
Because they can then lift the steel easily without having to put chains and lifting gear onto it.
Which has a stronger magnetic field a solenoid or a electromagnet?
An electromagnet typically has a stronger magnetic field than a solenoid. This is because an electromagnet uses a ferromagnetic core, such as iron, to enhance its magnetic strength, while a solenoid is simply a coil of wire without a core.

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
What is stronger an electromagnet with 20V and 5A or one with 5V and 20A?
The strength of an electromagnet depends on the current through the coil andthe number of turns in the coil. The voltage across the coil doesn't matter at all.So IF both of your electromagnets have the same number of turns in their coils,then the one with 20A of current is stronger than the one with 5A of current.If they have different numbers of turns in their coils, then we need more informationbefore we can decide which one is stronger.

A bar magnet's pull is strongest?
No, electromagnets are stronger than bar magnets.
Why will an electromagnet be able to pick up more steel cans than a permanent magnet?
An electromagnet is a stronger magnet.
What are the advantages and disadvantages do electromagnets have?
There are many reasons why electromagnets shouldn't be used. For example, permanent magnets are better to use economically because there is no cost of operation, like an electromagnet. There is also no maintenance or hardly any setup required. For permanent magnets, they can be used for a lot longer than electromagnets becausecan be used in hazardous places and are they are unaffected by shock or vibrations. Electromagnets require electricity to run, which costs money. They also burnout or lose its magnetism after a while. There are also many reasons why electromagnets should be used. For an electromagnet, a person could easily control the power of the magnetism, unlike the permanent magnet which has the same intensity throughout. A person could also turn the power of the magnet on and off, which can become useful in certain situations. An electromagnet can also be made stronger than permanent magnets. The electromagnet also has a good field of depth, unlike the permanent magnets limited field depth.

Are bar magnets stronger than electro magnets?
Yes, because electromagnets can lose their magnetism.
What makes a electromagnet stronger than a solenoid?
The strength of an electromagnet is determined by the number of windings, the current flowing through the windings, and the permeability of the core.
Why is a crane in a steelworks fitted with a large electromagnet?
Because they can then lift the steel easily without having to put chains and lifting gear onto it.
