Magnetism does not affect the resistance of a conductor. The factors affecting resistance are the conductor's length, cross-sectional area, and resistivity. As resistivity is affected by temperature, temperature indirectly affects resistance.
However, the changing magnetic field surrounding a conductor carrying an AC current causes the current to flow closer to the surface rather than being distributed throughout the cross-section of the conductor. The greater the frequency, the greater this effect. This has the equivalent effect of reducing the cross-sectional area of the conductor, causing its resistance to rise. This is misleadingly called the 'AC resistance' of the conductor!

What is the only insulator from magnetism?
A superconductor is the only material that completely repels magnetic fields, acting as an insulator from magnetism. This phenomenon is known as the Meissner effect, where a superconductor expels magnetic fields from its interior when it transitions to a superconducting state.
What is difference between residual magnetism and retentivity?
Residual magnetism and remanence are the same thing. The term residual magnetism is often used in engineering applications. Both terms describe the magnetization, and measure of that magnetism, left behind in a ferromagnetic material after the external magnetic field is removed.
What is the difference between magnetism and electricity?
The difference between electricity and magnetism is that you must be in the same frame of reference as the electric field to experience electricity, because all that magnetism is, is electricity moving relative to you.Although they are two different forms of energy, you can use magnetism to create electricity and you can use magnetism to create electricity.Electricity is the flow of energy or current through a metallic substance. Magnetism is the attraction of the metallic molecules in a solid or substance.
What is the sure test of magnetism?
The sure test of magnetism is the ability of a material to attract iron or other magnetic materials. If a material attracts iron, it is considered to be magnetic.
Which branch of science includes magnetism?
Physics is the branch of science that includes the study of magnetism. Magnetism falls under the broader category of electromagnetism, which deals with the interactions between electric and magnetic fields.
Does magnetism have an effect on gravity?
No.
One important effect derived form electricity?
Magnetism
What one of these is not a force gravity magnetism electricity or air resistance?
Air resistance is not a fundamental force like gravity, magnetism, and electricity. It is a type of frictional force that occurs when an object moves through the air and affects the motion of the object.
What part of the atom would effect magnetism?
the electrons! hope i helped! <3 (:
What is effect of resistance in heat production in a current carrying conductor?
resistance will be high
How does magnet affect growth of seed?
They don't. Magnets and magnetism has no effect on seed or plant growth whatsoever.
Are lcd TV's effected by speakers the way tube TV's are?
No. There's no effect from magnetism in an LCD TV.
Which of these is not a way by which objects can become charge?
magnetism magnetism magnetism
What is environmental resistance and what effect does it have on population?
Penis
What can reduce the effect of air resistance?
Reducing the speed of the object or increasing its surface area can help reduce the effect of air resistance. Streamlined shapes and smooth surfaces can also minimize air resistance.
What are 5 examples of magnetic forces?
polarized atomic regions (a magnetic substance) electron-induced magnetism (induction) radio-induced magnetism (radio waves induce current on a conductor that in turn is creates electron induced magnetism) reverse-magnetostriction (the opposite of the effect that states magnetism causes metal to change shape on the atomic level) a flawless LRC circuit
