How can we change the direction of the magnetic field in a current carrying circular loop?

How can we change the direction of the magnetic field in a current carrying circular loop?

The magnetic field around a straight current carrying conductor or wire can be increased by bending the wire into circular loop. A circular loop is made up of large number of very small straight wires.

How can the direction of force on a current carrying conductor placed in magnetic field be reversed?

The direction of force on a current carrying conductor placed in a magnetic field cannot be reversed by reversing the direction of magnetic field.

What is the direction of the magnetic field surrounding a current carrying wire?

Simply stated, the Right Hand Rule says that the magnetic field lines produced by a current-carrying wire will be oriented in the same direction as the curled fingers of a person’s right hand (in the “hitchhiking” position), with the thumb pointing in the direction of the current flow.

What is the direction of magnetic field at a point outside the surface of the loop?

Direction of magnetic field at centre for the loop carrying current in clockwise direction is perpendicular to the plane and is inward (going into the plane) which is south pole shown in the figure below. For the point outside the surface of the loop the direction is outwards (going outside of the plane).

What is the direction of the magnetic field due to the magnet in the center of the coil?

The standard right hand grip rule can be modified to predict the direction of the magnetic field. If the right hand fingers curl round the coil in the direction of the current, then the thumb points in the direction of the magnetic field down the centre of the coil.

How is a current carrying wire placed in a magnetic field so that magnetic field does not act on it?

A current carrying wire is placed (A) Parallel to magnetic field so that magnetic field does not act on it. Explanation: When the current carrying wire is placed in a magnetic field, then the wire is subjected to magnetic force.

What is the direction of a magnetic field?

The direction of magnetic field lines is defined to be the direction in which the north end of a compass needle points. The magnetic field is traditionally called the B-field.

What is the difference in the pattern of magnetic field?

The only difference is circular loop has only one turn,so its induced north and south pole are just opposite and very close. In solenoid the induced south and north pole are some distance apart,as it has more number of turns.

When a current carrying circular loop is equivalent replaced by magnetic dipole?

Answer : When we replace a current carrying circular loop with an equivalent magnetic dipole, the quantity that is not altered is ‘Magnetic moment’.

What is magnetic field direction?

• The direction the magnetic field produced by a. moving charge is perpendicular to the direction of motion. The direction of the force due to a magnetic field is perpendicular to the direction of motion.

In which direction do the magnetic field lines point near the South Pole of a magnet?

Near the South Pole, inside the magnet, the field lines are moving parallel to each other towards the North Pole. So inside the magnets the field lines are always moving towards the North from the south and outside the magnet the field lines are moving from the north to the South.

What happens when a conductor is placed in a magnetic field?

So, it can be concluded that, when the current carrying conductor is placed in the magnetic field, the conductor experiences a force and moves due to the field. The direction of the force acting on the conductor can be changed by changing the direction of the magnetic field.

How can the direction of force acting on a conductor be changed?

The direction of the force acting on the conductor can be changed by changing the direction of the magnetic field. When a current-carrying wire is placed in a magnetic field, a force is exerted on the wire. Fleming gave a simple rule to determine the direction of the force acting on the current-carrying wire placed in a magnetic field.

What is the direction of magnetic field lines of force?

The direction of the magnetic field lines of force around a conductor is given by Maxwell’s right-hand grip rule or the right-handed corkscrew rule. This proves that the direction of the magnetic field also depends on the direction of the current in the conductor. This is given by Maxwell’s rule.

What is the relationship between electromagnetism and current?

Whenever electrons flow through a conductor, a magnetic field is created around the conductor. This important relationship between electricity and magnetism is known as electromagnetism, or the magnetic effect of current. When DC current flows, the magnetic field will act in one direction, as illustrated in Figure 1.
