How does changing current affect the magnetic force on a wire suspended in a magnetic field?

Current passing through a wire in a magnetic field creates its own magnetic force in some direction. If you increase the current, force will be increased. If the direction of current is changed, direction of force will also be reversed. Direction of current is found by applying right hand rule.

1. If the Magnetic Field is CHANGING, then it can INDUCE a Current in the conductor.
2. The EXTERNAL magnetic field can either attract or repel the conductor, causing it to vibrate, or bend.

∙ 13y agothe magnetic fields around each coil of wire add together to form a stronger magnetic field inside the coil :)
Wiki User
∙ 12y agoYou use a magnetic field to induce a current in a wire by moving them in relation to each other, or by varying the strength of the magnetic field.

Can an electric current be used to affect a compass needle?
Yes. Any electric current is surrounded by a magnetic field.
Why do factors effect electromagnets?
The factors that affect the power of electromagnets are: the current (amperes), the amount of coils, and whether a soft iron core is present. These affect the electromagnet because the current is what provided the electrical energy which created the magnetic field, and so the greater the current, the stronger the magnetic field; the amount of coils is a measure of the resistance provided by the wire, and so the greater that is, the more electrical energy is being used to strengthen the magnetic field; finally, the soft iron core further strengthens the magnetic field as it can be temporarily magnified, so it will become a magnet itself.

How can you make an electromagnet stronger and why?
An electromagnet will maintain a charge as long as current continues to flow through it. Strengthening the charge is a matter of changing, or adjusting the components that enable the charge to flow. There are many ingredients that affect electromagnet strength. The length and width of the magnetic field, the amount of resistance the current encounters, the pulling power of the magnet itself, all determine how strong your electromagnet will be.
What factors of an electromagnet affect the strength of the magnetic field?
One of them is how many coils go around the electromagnet. also the amout of current flow< and the type of core material.
Can a magnetic field affect the performance of electrical circuits?
You better believe it can, but only if it's changing, otherwise the magnetic field can just pull or push the electrons in the circuit towards or away from it, but it can't slow them down. If the magnetic field is changing, a phenomenon called inductance happens. Inductance is an applied current to a circuit by a changing magnetic field. As you might imagine, an additional applied current to a circuit can definitely change the circuit's behavior and alter its performance.
Does current affect electromagnetism?
Does current affect electromagnetism? No. Does current affect magnetic fields? Yes. The laws (Maxwell's Equations) pertaining to electromagnetism is constant and will not change regardless of current applied. However, Maxwell's equations does dictate that a change in current will essentially result in a change in magnetic fields. Current flow will produce a magnetic field perpendicular to the current direction.
What are 3 factors which affect the magnitude of magnetic force on current-carrying conductors?
Electric current, magnetic field intensity, length of the conductor, angle between the electric current and magnetic field
How does the changing the battery voltage affect the current?
If voltage varies then current varies with constant resistance.
Can an electric current be used to affect a compass needle?
Yes. Any electric current is surrounded by a magnetic field.
What do you mean by magnetic affect of electric?
The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.

What affect does a changing magnetic field strength have on an ac generator power output?
By increasing the field current (current flowing through the rotor windings), the magnetic field generated by these windings will increase. This increased magnetic field will result in a larger current flow in the stator windings (the output of the generator). This in turn causes a larger pull against the rotation of the rotor, causing it to slow down. The governor will then kick in, allowing more steam/ power to the prime mover to keep speed steady. Assuming all is working correctly, the output power will increase as the magnetic field is increased (to a limit).
Can a electric current affect a compass?
Yes. An electric current is surrounded by a magnetic field, and this will affect a compass. Please note that this is more noticeable in the case of DC - for AC, the current changes all the time, it changes very quickly, and the AVERAGE value of the magnetic field is zero.
What variables affect the behavior of electromagnets?
Primarily the current and the number of turns. Also more subtle factors such as the magnetic properties of the core.
Which factors affect the magnetic strength of a solenoid which is carrying an electric current?
Factors affecting the magnetic field strength of a solenoid are: - length of the solenoid - diameter of the solenoid - current through the coil around the solenoid - number of turns of the coil of current around the solenoid, usually turns of wire - material in the core
