What is the force on a current carrying wire in a magnetic field?

The magnetic force on a current-carrying wire through a magnetic field is given by F = IL x B . When a current is passed through a magnetic field, the magnetic field exerts a force on the wire in a direction perpendicular to both the current and the magnetic field.

What happens to the force acting on a current carrying conductor?

Answer: The expression of magnetic force id defined as F = CIL Sin theta. (a) Hence, as the current, I in the conductor increases, the force also increases . (b) As the length of the conductor, L increases, the force on the conductor also increases proportionately.

Why and when does a current carrying conductor?

When a current-carrying conductor is placed in a magnetic field the wire experiences a force due to the interaction between the field and the magnetic field produced by the moving charges in the wire . ... That is why the conductor experiences a force.

How do you calculate electromagnetic force?

The entire electromagnetic force F on the charged particle is called the Lorentz force (after the Dutch physicist Hendrik A. Lorentz) and is given by F = qE + qv × B.

What is the relationship between force and current?

What is the relationship between force and current? Force is directly proportional to current ; as the current that passes through the wire increases, so does the magnetic force.

Is current carrying conductor a permanent magnet?

It is a permanent magnet It is a temporary magnet. Its magnetism is only for that duration till the current flows through it.

What two things can be done to increase the force on a current carrying conductor according to the motor principle?

(b) The force on the conductor is directed to the left. (c) The force on the conductor will be directed into the page. 2. To increase the force on a current-carrying conductor, increase the magnitude of the external magnetic field or increase the magnitude of the electric current through the conductor.

Why no force acts on a current carrying conductor when it is parallel to the magnetic field?

Answer: No force acts on a current carrying conductor when it is placed parallel to the magnetic field. For example:- You can see in a DC motor, the coil which is parallel to the magnetic field lines does not experience a force, but the coil which is perpendicular to the magnetic field lines experiences.

What happens to the force when current increases?

If the current is doubled the force on the conductor will double. If the current is is reduced to a third of the initial value the force will also reduce to a third of its initial value. If the current is increased by five times the force will also increase by five times.

How will the force in a current carrying conductor change if current in the conductor is increased?

The magnitude of the force increases when the current is increased.

Why and when does a current carrying conductor kept in a magnetic field experience force list the factors?

(i) A current carrying conductor has a magnetic field associated with it . The two magnetic fields, one due to the magnet and the other due to the current in the conductor, interact. This produces a force on the conductor. (b) the strength of the magnetic field.

On what factor does the force experienced by a current carrying conductor placed in a uniform magnetic field depends?

Answer Expert Verified

the factors on which force on current carrying conductor depends are : the strength of magnetic field being passed on the conductor , the current being passed through the conductor, the length of the conductor .

What is meant by electromagnetic force?

What is Electromagnetic Force? The electromagnetic force is a type of physical interaction that occurs between electrically charged particles . It acts between charged particles and is the combination of all magnetic and electrical forces. The electromagnetic force can be attractive or repulsive.

How do you find current magnetism?

Another version of the right hand rules can be used to determine the magnetic field direction from a current— point the thumb in the direction of the current , and the fingers curl in the direction of the magnetic field loops created by it.

What is the direction of force that is exerted on a current carrying conductor kept perpendicular in external magnetic field?

A current carrying conductor placed in a magnetic field experiences a force. If the direction of the field and that of current are mutually perpendicular to each other, then the force acting on the conductor will be perpendicular to both and that can be determined using the Fleming’s left-hand rule.

What is electromagnetic force measured in?

It is abbreviated E in the international metric system but also, popularly, as emf. Despite its name, electromotive force is not actually a force. It is commonly measured in units of volts , equivalent in the metre–kilogram–second system to one joule per coulomb of electric charge.

Is force perpendicular to current?

The magnetic force on a current-carrying wire is perpendicular to both the wire and the magnetic field with direction given by the right hand rule.

What happens when the current carrying conductor is placed along the direction of magnetic field?

When a current carrying conductor is placed in a magnetic field, a mechanical force is exerted on the conductor which can make the conductor move .

Does a current carrying wire produces electric field?

Yes there is an electric field outside of a current carrying wire, in a direction along the wire axis (i.e. parallel to the wire).

Why is a current carrying conductor a magnet?

Magnetic field is generated by moving charge, so a current carrying conductor has flowing electrons in it , hence it has a magnetic field around in the form of concentric rings.

What is the current carrying?

The current-carrying conductor generates a magnetic field around it . This interacts with an external magnetic field. When two magnetic field interacts attraction & repulsion between them based on the direction of external magnetic field and the direction of current in the conductor.

How do you increase the force of a wire?

If the current-carrying wire is placed in a magnetic field (whose lines of force are at right angles to the wire) then it will experience a force at right angles to both the current direction and the magnetic field lines. The force increases if the strength of the magnetic field and/or current increases .

When the current in the current carrying conductor increases what happens to the force in the conductor which is at right angles to the magnetic field?

Explanation: The force at right angles to the magnetic field of a current carrying conductor increases when the current increases because it is directly proportional to the force .

When a current carrying conductor is placed parallel to the magnetic field maximum force act on the conductor True or false?

No force acts on a current carrying conductor when it is parallel to the magnetic field.

What happen when a current carrying loop is placed inside a non uniform magnetic field?

Hint The question is saying that a current- carrying loop is placed in a non- uniform magnetic field. Since the magnetic flux is non-uniform the change in magnetic field intensity will apply a force on the current- carrying loop and as a result, it’ll also apply a torque that is generated during the process.

What is the condition of electromagnetic induction?

The condition necessary for the production of current by electromagnetic induction is that there must be a relative motion between the wire and the magnet.

What happens to the direction of the force on a current carrying wire immersed in a magnetic field when the current is reversed?

Since the directions of the two currents are opposite, the magnetic field from one wire is opposite to the other . This means the magnetic fields will cancel each other to some extent.

What are the factors on which the force acting on a given current carrying conductor placed in a magnetic field depend State when is the magnitude of force highest?

The magnitude of the force on a current carrying conductor increases when the strength of the magnetic held is increased . The magnitude of the magnetic force also depends on the length of the wire in the magnetic field. The longer the wire in the magnetic field, the larger the force on the wire as shown in Figure.
