How is a simple electromagnet created?
By passing an electric current through any conductor, a magnetic field will be created. Therefore, a simple electromagnet can be created by connecting a power source to a coil of copper wire.
What is the magnetic field of an electromagnet similar to?
a bar magnet...
How does coiling a wire affect the magnetic field generated an electromagnet?
Coiling a wire increases the magnetic field of an electromagnet because the magnetic field around a wire is circular and perpendicular to the wire. Each turn of the wire reinforces the field of the one next to it. The magnet field is strengthened. (I was in A+, too ;) ) - Dawn Ayers
What is Elctromagnetic?
An electromagnet is created by winding a coil of wire around an iron core. Electrical current is passed through the wire, which creates a magnetic field. Something that is electromagnetic is anything that is an electromagnet.
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
What does a electromagnet create?
a magnetic field
Can an electromagnet create a magnetic field when the battery is removed?
If the electromagnet has a core, which has become magnetized, then the core will have a residual magnetic field when the power is removed.
Is Venus electromagnet?
No. Venus has no magnetic field.
When does an electromagnet produce a field?
An electromagnet produces a magnetic field when current is passed through it wire winding.
What is difference between of Electromagnet and Electric Magnetic Field?
An electromagnet is a magnet that only generates magnetic forces when electricity is running through it, basically a magnet that can be turned on and off. An electromagnetic field is the magnetic force generated when an electromagnet is used.
How is a simple electromagnet created?

What is a region where a magnetic force can be detected?
The magnetic field. If it's an electromagnet, the electromagnetic field.
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
What happens when you decrease the current in an electromagnet?
When you decrease the current in an electromagnet, the magnetic field decreases.
The magnetic field of an electromagnet is similar to that of a magnet?
bar
What is the magnetic field of an electromagnet similar to?
a bar magnet...
How is a magnetic force in an electromagnet created?
An electromagnet uses electricity to create the magnetic field. Moving charges create magnetic fields. Knowing that, if we have a lot of copper wire (with a suitable insulator) wrapped around an iron core, we can send direct current through that wire, and it will create a magnetic field. The magnetic field will magnetize the iron core, and the core becomes a magnet. Wrapping wire around a nail and connecting a battery to the ends of the wire will make a simple electromagnet.
