What will happen to the magnetic field if radius is increased?

Answer: as we increase the radius of the coil , it’s magnetic field at the centre reduces .

Does radius of wire affect magnetic field?

The circumference of a circle is proportional to its radius and the magnetic field just described is inversely proportional to radius. Therefore the integral around the circumference of any circle around the wire of the component of magnetic field in the direction of the path is independent of its radius.

What is the relation between the radius and the magnetic field strength?

Hence, as the radius of the coil increases both the magnetic field intensity and the magnetic flux density decreases, and vice versa.

What happens to the magnetic field when the radius of the loop is doubled at its original value and at the same time current passing through it is also doubled?

Explanation: If we double the radius of a coil keeping the current through it unchanged, then the magnetic field at any point at a large distance from the centre becomes approximately.

Why does radius decrease when magnetic field increases?

Some of the electrons come out as a narrow beam through the slit S in the side of C. The magnetic field of the Helmholtz Coils causes the stream of electrons to move in a circular path the radius of which decreases as the magnetic field increases.

Is magnetic field strength inversely proportional to radius of circular coil?

Factors affecting the strength of magnetic field 2. The magnitude of magnetic field is inversely proportional to the radius of the circular loop.

How the magnetic field produced due to circular coil depends on its radius?

Strength of magnetic field is directly proportional to current. Strength of magnetic field is inversely proportional to radius of circular wire. The deflection of needle of magnetic compass placed at the centre of circular wire of smaller radius is more than that placed at centre of circular wire of larger radius.

What happens to magnetic field at the centre of circular coil when its radius is doubled keeping current constant?

The magnetic field at the centre of the circular coil, B = I r μ 0 I 2 r . Hence, if we double the radius, the magnetic field at the centre of the coil will become half its original value.

What happens to the magnetic field at the center of the circular coil when its radius is doubled keeping current constant?

what happens to the magnetic field at its centre? doubled. becomes four times. remains unchanged.

How do you find the magnetic field inside a conductor?

Magnetic Field Inside a Conductor. The magnetic field inside a conductor with uniform current density J = I/πR 2 can be found with Ampere’s Law. Inside the conductor the magnetic field B increases linearly with r. Outside the conductor the magnetic field becomes that of a straight conductor and decreases with radius.

How does a magnet interact with a moving charge?

Magnetic Field. Interaction of magnetic force and charge – The moving charge interacts with the fixed magnet. The force between them is at a maximum when the velocity of the charge is perpendicular to the magnetic field.

What is the difference between electric and magnetic field?

Magnetic Field. Electric field : 1) A distribution of electric charge at rest creates an electric field E in the surrounding space. 2) The electric field exerts a force F E = q E on any other charges in presence of that field. Magnetic field: 1) A moving charge or current creates a magnetic field in the surrounding space (in addition to E).

How can I increase the magnetic field in the solenoid?

Of the following choices, the most effective way to increase the magnetic field in the interior of the solenoid is: a) Double its length, keeping the number of turns per unit length constant. b) Reduce its radius by half, keeping the turns per unit length constant.
