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
A device that produces a magnetic field by wrapping wire into a coil is a?
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
How is an electromagnet different from a refrigerator magnet?
A refrigerator magnet is magnetic because it is a "permanent" magnet. An electromagnet is a magnetic field caused by a current flowing through a wire.
What happens when the electric current is reversed on am electromagnet?
When an electric current is reversed in an electromagnet, the magnetic field also reverses.
The magnetic field of an electromagnet is similar to that of a magnet?
bar
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.
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.
When a magnet that has a magnetic field only when there is electricity is called?
An Electromagnet
What cause electromagnet cause motion?
because of the magnetic field.
Can an electromagnet have an aluminum core?
The magnetic field will be not be as strong. It will be weaker.
