What is advantage of using radial magnetic field?

The radial magnetic field is always parallel to the plane of the coil of the galvanometer, and provides constant torque irrespective of the rotation of the coil. This makes the deflection directly proportional to the current, and facilitates easy calibration of the galvanometer scale.

What is the use of radial field in galvanometer?

The radial magnetic field is used in a suspended coil galvanometer to provide a uniform torque on the coil because it provides a uniform magnetic field. It ensures that the magnetic field is radial and uniform throughout the area of the coil.

What is radial magnetic field and how it is produced?

Radial magnetic field is a type of magnetic field which is radial in nature. It is produced in a moving coil galvanometer. This condition could be achieved in a moving coil galvanometer by using pole pieces having concave surfaces inside and by using a soft iron core within the coil.

What is a radial magnetic field?

Answer: A radial magnetic field is a magnetic field wherein the coil’s plane stays parallel to the magnetic field’s direction in all positions. The radial magnetic field is also parallel to the coil plane of the galvanometer, which creates constant torque regardless of the rotation of the coil.

What is radial field?

A field in which the field lines are radii that radiate from a centre. Point charges and masses and spheres have radial fields. The point sources of the fields and the centres of the spheres are the centres from which the field lines radiate.

What is radial magnetic field?

Is radial magnetic field uniform?

It falls off as 1/R2 but is uniform in theta and phi. A uniform radial magnetic would be formed by a magnetic monopole similar to that of an electric point charge. All of the magnetic fields we observe are dipole fields caused by loops of current or spins of particles.

What is the function of uniform radial field and how it is produced?

In uniform radial field sinα = 1, so the torque acting on the coil will always be τ = nIBA (maximum). To produce radial magnetic field pole pieces of permanent magnets are made cylindrical and a soft iron core is placed between them. The soft iron core helps in making the field radial.

What is radical magnetic field?

The magnetic properties of free radicals provide a powerful tool for their detection and study. Free radicals, however, are paramagnetic (attracted by a magnet) because of the spin of the odd electron, the spins of the remaining paired electrons effectively canceling each other. …

What is a radial magnet?

Radial Magnets Radially-oriented ring magnets are a unique subset of NdFeB sintered magnets. Using proprietary technologies, a multipole ring can be sintered into a truly radial geometry. This replaces the costly and labor-intensive method of gluing arcs, bread loaves or rectangular segments onto a rotor shaft.

What is the function of radial magnetic field and soft iron core used in it?

By making a uniform radial magnetic field through a coil, the magnetic field lines become perpendicular to the magnetic moment of a galvanometer. Soft Iron core can make the electromechanical field radial which in turn would increase the magnetic field.

How is radial magnetic field achieved in case of galvanometer?

Magnet is taken in the form of horse- shoe.
