Quick Answer: What Happens To A Current Carrying Wire In A Magnetic Field If The Current Is Reversed?

What law gives the direction of induced current?

Lenz’s law is used for determining the direction of induced current.

Lenz’s law of electromagnetic induction states that the direction of induced current in a given magnetic field is such that it opposes the induced change by changing the magnetic field..

Which statement describes the result of reversing the current in a current carrying wire in a magnetic field?

Which statement describes the result of reversing the current in a current-carrying wire in a magnetic field? It causes the force deflecting the wire to be perpendicular to the magnetic field, but in the opposite direction.

What happens to the direction of the force on a wire when the current in it is reversed?

If the forefinger points in the direction of the magnetic field and the middle finger in the direction of the current, then, the thumb points in the direction of the force exerted on the conductor.So, if the current is reversed in the conductor placed in a magnetic field the direction of force is also reversed.

What will be the direction of force?

The direction of the force can be found using the right-hand-slap rule. This rule describes the direction of the force as the direction of a ‘slap’ of an open hand. As with the right-hand-grip rule, the fingers point in the direction of the magnetic field.

What will happen when the direction of current in the solenoid is reversed?

The direction of magnetic field is always perpendicular to the direction of current flow and the magnitude of the magnetic field inside a solenoid is directly proportional to the current flowing through the solenoid. Thus,when the current through the solenoid is reversed,the direction of magnetic field is reversed.

Is affected by changing the direction of flow of current in the conductor?

Explanation: As the direction of the electric current changes, the direction of the magnetic field also gets reversed. If the direction of electric current in a vertically suspended current carrying conductor is from south to north, the magnetic field will be in the anticlockwise direction.

Why magnetic field is strong inside the solenoid?

When a direct electric current is passed through it, the shape of the magnetic field is very similar to the field of a bar magnet. The field inside a solenoid is strong and uniform. The small magnetic fields caused by the current in each turn of the coil add together to make a stronger overall magnetic field.

Why does magnetic field depends on moving charges only?

What is the mechanism by which one magnet exerts a force on another? The answer is related to the fact that all magnetism is caused by current, the flow of charge. Magnetic fields exert forces on moving charges, and so they exert forces on other magnets, all of which have moving charges.

What happens if there is no change in the direction of current in the coil of wire which is kept in uniform magnetic field?

Answer. If there is no change in the direction of the current in the coil of wire, it shows the property of the magnetic force acting on the moving charged particles. The free electrons move towards the positive end of the conductor with some velocity. As a result of this, magnetic force acts on them.

What happens if you reverse the current in an electromagnet?

The two poles of the permanent magnet remain the same, but the poles of the electromagnet reverse when the direction of electric current reverses. For example, the end of the electromagnet which is its north pole will be attracted to the south pole of permanent magnet.

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

A larger current in the conductor will result in a larger force acting on it if the strength of the magnetic field is kept constant, as shown in Figure. The magnitude of the force on a current carrying conductor increases when the strength of the magnetic held is increased.

What is the direction of the magnetic force on the current in a )?

The magnetic field exerts a force on a current-carrying wire in a direction given by the right hand rule 1 (the same direction as that on the individual moving charges). This force can easily be large enough to move the wire, since typical currents consist of very large numbers of moving charges.

Does current carrying wire has a magnetic effect around it yes or no?

When a current flows in a wire, it creates a circular magnetic field around the wire. This magnetic field can deflect the needle of a magnetic compass. The strength of the magnetic field is greater closer to the wire, and increases if the current increases.

What happens to a wire carrying a current in a magnetic field?

A current-carrying wire or coil can exert a force on a permanent magnet. … 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.

How can you reverse the direction of the magnetic field around an electromagnet?

The magnetic field around an electromagnet is just the same as the one around a bar magnet. It can, however, be reversed by reversing the current (turning the battery around).
