How are magnetic field and magnetic force related?

Table of Contents

The magnetic force F is proportional to the charge and to the magnitude of velocity v times the magnetic field B. Depending on the initial orientation of the particle velocity to the magnetic field, charges having a constant speed in a uniform magnetic field will follow a circular or helical path.

What is magnetic field and force?

magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.

What is magnetic force Class 12?

Magnetic force is a consequence of electromagnetic force and is caused due to the motion of charges. We have learned that a moving charge surrounds itself with a magnetic field. With this context, the magnetic force can be described as a force that arises due to interacting magnetic fields.

What is magnetic force law?

The magnetic force is proportional to q and to the magnitude of the vector cross product v × B. In terms of the angle ϕ between v and B, the magnitude of the force equals qvB sin ϕ. An interesting result of the Lorentz force is the motion of a charged particle in a uniform magnetic field.

What is the example of magnetic force?

Examples of magnetic force is a compass, a motor, the magnets that hold stuff on the refrigerator, train tracks, and new roller coasters.

What is magnetic force called?

Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. Each atom has electrons, particles that carry electric charges.

What are two types of magnetic forces?

The two types of magnetic forces are attractive magnetic forces and repulsive magnetic forces. The former pulls two magnetic substances towards each other and the latter pushes them away from each other.

What is magnetic field and example?

1. The definition of a magnetic field is a place in space near a magnet or an electric current where a physical field is created from a moving electric charge that creates force on another moving electric charge. An example of a magnetic field is the Earth’s magnetic field. noun. 2.

Why is magnetic force important?

Magnetic forces can be used to aid humans through technology. Anything that is powered by electricity wouldn’t work without magnets, because we use them to generate electricity.

What is in a magnetic field?

“A magnetic field is the area around a magnet, magnetic object, or an electric charge in which magnetic force is exerted.”

What is SI unit of magnetic field?

Magnetic field is denoted by B and H. The SI unit of H is amperes per metre and the SI unit of B is Newtons per metre per ampere or Teslas.

What is called magnetic field?

The magnetic field is the area around a magnet in which the effect of magnetism is felt. We use the magnetic field as a tool to describe how the magnetic force is distributed in the space around and within something magnetic in nature.

What uses magnetic force?

Computer hard drives use magnetism to store the data on a rotating disk. More complex applications include: televisions, radios, microwave ovens, telephone systems, and computers. An industrial application of magnetic force is an electromagnetic crane that is used for lifting metal objects.

What is use of magnetic field?

Magnetic fields are used throughout modern technology, particularly in electrical engineering and electromechanics. Rotating magnetic fields are used in both electric motors and generators.

What is the unit of magnetic force?

The unit of magnetic field is tesla. It is the SI unit of magnetic field. Magnetic field is the measure of magnetic flux (Φ) per unit area. 1tesla=1wb/m2.

What is the magnetic field in physics?

The magnetic field is described mathematically as a vector field. This vector field can be plotted directly as a set of many vectors drawn on a grid. Each vector points in the direction that a compass would point and has length dependent on the strength of the magnetic force.

How does a magnetic field exert force?

2) The magnetic field exerts a force Fmon any other moving charge or current present in that field. – The magnetic field is a vector field vector quantity associated with each point in space. Fm = qv⊥B= qvBsin ϕ F qvB

What are the magnetic forces between two bodies?

– The magnetic forces between two bodies are due to the interaction between moving electrons in the atoms. – Inside a magnetized body (permanent magnet) there is a coordinated motion of certain atomic electrons .
