Lenz’s Law
Which law describes the magnetic field in a nonlinear wire?Lenz’s Lawstates that the induced tensions will be such that they oppose the variation of the magnetic flux that produced them; However,this law is a consequence of the principle of conservation of energy.

Which describes the magnetic field lines near a long straight wire?

The length element in the direction of the current is crossed into a vector directed from that element toward the point of measurement. Which describes the magnetic field lines near a long straight wire carrying current? They form concentric circles around the wire, in a plane perpendicular to the wire.

What is the rule for the interaction of magnetic poles?

Gravity Created by melaniesanchez_ Terms in this set (113) The rule for the interaction of magnetic poles is similar to the rule for electric.. A) circuits.

Which describes the magnetic force on each wire due to current?

The force on each current is perpendicular to the current and toward the other current. We set up two parallel currents in opposite directions. Which describes the magnetic force on each wire due to the other wire? The force on each current is perpendicular to the current and away from the other current.

What is the difference between an electromagnet and a conductor?

QUESTION Electromagnets can use ferromagnetic materials in a core. these materials concentrate magnetic fields much better than other substances. In a conductor, conductor field has to move to produce change in the strength 2 answers QUESTION

What is the result of integrations parallel to the length of the solenoid?

The integrations parallel to the length of the solenoid give a nonzero result; those perpendicular to the length give a zero result.

What is the force on each current?

The force on each current is perpendicular to the current and toward the other current.

Which part of the Amperian loop gives the direction of the current?

The fingers give the direction of integration. The thumb gives the direction of a positive current through an Amperian loop.

Where is the field maximum?

The field is maximum at the surface and progressively smaller as you move away from the surface, either toward the center or away from the center.
