The strength of the electromagnet depends on the magnitude of the current in the coil around it.
The voltage required is only what produces the desired current in the coil. Since the coil is nothing but
wire, the resistance is quite low, and a relatively small voltage produces a relatively large current.

How do you make an electromagnet field stronger?
You could either put a bar of iron in the center of the electromagnet, increase the voltage that you put in, or make more loops of wire.
Is a toothpick a part of an electromagnet?
Not generally, although MacGuyver could make an electromagnet with a toothpick and a spool of wire.
What kind of energy does an electromagnet make?
Electrical to Mechanical
Would spinning the loops on an electromagnet make it stronger?
Yes, if you increase the number of coils or loops in an electromagnet, it's power increases.
How do you make an electromagnet weak?
reducing the number of coils around the core or by reducing the current in an electromagnet, will cause the magnetic power to weaken.
How will you make an electromagnet stronger without changing the electric cell fitted to the circuit?
Adding more turns of wire to the electromagnet will make it stronger without changing the applied voltage.
How do you make a electromagnet stronger?
For a simple copper wire around iron nail electromagnet, increasing the number of rounds the copper wire makes around the nail will increase the electromagnet's strength. Also, increasing the voltage applied(adding a battery) will increase the magnetic field.
How do you make an electromagnet field stronger?
You could either put a bar of iron in the center of the electromagnet, increase the voltage that you put in, or make more loops of wire.
Can you make an electromagnet with aluminum wire?
No. You should use a wire with the best electric conductivity (copper or silver) and wrap it around a (soft) iron core. The wire creates the magnetic field, the iron core concentrates it and turns into a magnet when a voltage is applied to the wire. Iron has rather poor conductivity and malleability so is not suited as the coil of an electromagnet.
When measuring resistance should there be a voltage applied to the resistor?
No, the meter used to make the measurement will be applying whatever voltage to the resistor it needs to make the measurement. Any additional voltage will disturb this, resulting in at least an incorrect reading and at worst damaging or destroying the meter.
How do you make a railway signal using electromagnet?
how to make road rail signal using electromagnet
To what should Islamic teachings need to be applied to?
The easy answer is that they should be applied to the choices we make. The hard part is determining how to apply them.
How to create a circuit that closes when activated?
Use (or make) an electromagnet as a control. Like the solonoid on your car's starter or power door locks Low voltage types available at Radio shack or the like...
How can you make an electromagnet stronger?
More wire wrappings, Larger Iron core, more and stronger electricity, etc
How do you check the operation of a multimeter?
For V, try it against a battery, or the mains ac voltage. For I, try (in series) it to measure the current through a known resistor with a known applied voltage. NEVER measure A against mains voltage!!! For Ohms, you should be able to try it against several known resistors. But make sure the internal batteries are OK beforehand.
How can the magnetic field strength of an electromagnet be reduced?
Either increasing the size of the current (in amps) or the number of turns of wire wrapped around the core will make a stronger magnet. A larger current will make a stronger magnet (up until too much makes the wire melt!). Increasing the voltage forces more current through the electromagnet.
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.
