Does the shape of the magnetic field change?

Does the shape of the magnetic field change?

When magnetized, certain bodies change their volume and linear dimensions. This phenomenon is called magnetostriction. The shape changes depend both on the properties of the magnetic field and on the substance structure.

Does the pattern of magnetic field depend on the shape of the conductor?

Yes, the pattern depends on the shape of the conductor. For example- Circular Loop and Straight current-carrying conductor.

How does magnetic field due to current carrying conductor vary?

The magnetic field produced due to a current-carrying conductor has the following characteristics: It encircles the conductor. Strength of the field is directly proportional to the magnitude of current. Strength of the field at any point is inversely proportional to the distance of the point from the wire.

What happens if current carrying conductor is placed in 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.

What happens when magnetic north changes?

Magnetic North and South Poles have even reversed or “flipped,” which is known as geomagnetic pole reversal. Geomagnetic pole reversals have happened throughout Earth’s history. Scientists have determined that, in the short-term, there is no real change to Earth’s environment and no threat to life due to a pole flip.

Do all magnetic fields have the same shape?

All magnetic fields do not have the same shape.

What is the pattern of magnetic field pattern due to current carrying conductor?

MAGNETIC FIELD PATTERN DUE TO STRAIGHT CURRENT-CARRYING CONDUCTOR. Like stationary charges produce an electric field proportional to the magnitude of charge, moving charges produce magnetic fields proportional to the current. In other words, a current carrying conductor produces a magnetic field around it.

What is the pattern of magnetic field pattern due to current carrying conductor long answer?

The Magnetic field lines around a straight conductor carrying current are concentric circles whose centres lie on the wire.

How the magnetic field vary when the current in a straight conductor increases?

Therefore, with increase in the magnitude of magnetic field the current flowing through the coil will increase. (ii) Magnitude of magnetic field at a point in a current carrying coil is inversely proportional to the distance. Hence, with increase in distance the magnetic field will decrease.

How does the strength of magnetic field due to current carrying conductor depends upon the current flowing and distance from the conductor?

(i) The strength of magnetic field is directly proportional to the current flowing in the conductor. If current is increased , then the magnetic field strength is increased . If distance is increased , then the magnetic field strength is increased . If distance is decreased , then the strength decreases .

What will happen if a current carrying conductor is placed in magnetic field How can the direction of magnetic field be found out?

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.

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 happens to the magnetic field around a conductor?

If the two parallel conductors are carrying current in opposite directions, the direction of the magnetic field is clockwise around the one conductor and counterclockwise around the other. This sets up a repelling action between the two individual magnetic fields, and the conductors would tend to move apart, as illustrated in Figure 5.

When does the direction of the magnetic field change?

The direction of the electric field gets reversed if the direction of electric current changes. Suppose a straight current-carrying conductor is hung vertically, and an electric current is flowing from north to south i.e from up to down. In this situation, the direction of the magnetic field will be clockwise.

How does length of wire affect magnetic force?

In this experiment we will investigate the effects of current, length of wire and magnetic field strength on the magnetic force. If a charged particle moves with some velocity, , through a uniform magnetic field, , it experiences a magnetic force given by

What is the relationship between current and magnetism?

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. AC current flow will produce a magnetic field that varies in direction with the direction of the electron current flow.
