How magnetic field lines look in hollow cylindrical electromagnet?
Wiki User
∙ 11y ago
Inside the hollow cylindrical electromagnet ("solenoid"), the magnetic field lines
are straight, parallel to each other, and parallel to the axis of the cylinder. They get
more complicated at the ends, but the above statement is good for a solenoid of
infinite length, which has no ends, and is a good approximation in the center of a
real one.

What is the magnetic field outside a hollow cylindrical wire?
B = mu .I / 2 .pi .r
Is Venus electromagnet?
No. Venus has no magnetic field.
What is a region where a magnetic force can be detected?
The magnetic field. If it's an electromagnet, the electromagnetic field.
Strong temporary magnet formed when a current is passed through a coil of wire?
A magnetic field.
How can you see the invisible magnetic field?
You can make magnetic field lines with a magnet. You an use a permanent magnet, or an electromagnet.
What is the magnetic field outside a hollow cylindrical wire?
B = mu .I / 2 .pi .r
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.
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...
When a magnet that has a magnetic field only when there is electricity is called?
An Electromagnet
