How magnetic field lines look in hollow cylindrical electromagnet?
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.
Why is the magnetic field produced by a cylindrical solenoid is similar to a cylindrical permanent magnet?
Simple Answer:The shape of the magnetic field of a uniformly wound solenoid is very nearly identical to the field produced by a uniformly magnetized permanent magnet with the same physical shape as the solenoid.For the Experts:This is a consequence of the mathematical equivalence of the source of the magnetic field as created by a current and the source of a magnetic field as created by the curl of the magnetization density of permanent magnet.
Is earth's magnetic field in an closed iron box more than the magnetic field outside the box?
No
Where is the strongest field in a toroidal magnet?
according to the ampere's law . magnetic field is strongest in a loop or a plane. and about toroid the magnetic is strongest in the coil where the wire is rotated around it . Magnetic field is minimum inside and outside the toroid.
Is magnetic field lines continuous?
Magnetic field lines are continuous. The lines outside the magnet go from north to south, while inside goes from south to north creating a closed loop. This is because there are no magnetic monopoles.

What are fero magnetic substance?
Ferromagnetic substance is items that can be magnetized by the outside magnetic field. It will stay magnetic after outside field is removed.

Where is the strongest area of magnetism in the field?
according to the ampere's law . magnetic field is strongest in a loop or a plane. and about toroid the magnetic is strongest in the coil where the wire is rotated around it . Magnetic field is minimum inside and outside the toroid.
Why is magnet unable to stick to a stainless steel refrigerator?
If a magnet doesn't stick to a material, that means that the material is non-magnetic. Every individual atom is a magnet, but in a magnetic material, there are groups of atoms (called "magnetic domains") that have their magnetic directions aligned. An outside magnetic field in such materials will align some of the magnetic domains in the direction of the magnetic field.
Why magnetic field outside the solenoid is zero?
The magnetic field outside a solenoid is not zero. This is only true for an infinitely (thus unreal) long solenoid. Infinitely long solenoids cannot be found in nature, but are often used as a good approximation of reality because they are much simpler to work with mathematically. The magnetic field outside a real solenoid is less dense than outside the solenoid and often one is only concerned with the field inside, which is approximately constant (deviations occur near the edges), so using an infinitely long solenoid is a good model.
Does Eris have a magnetic field?
