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. 

What is magnetic field and its unit?

The SI unit of magnetic field is tesla (T). 1 T is defined as the magnetic field in which a particle carrying a charge of 1 coulomb at a speed of 1 meter per second perpendicular to said field experiences a force with magnitude 1 newton, according to the Lorentz force law.

What is magnetic field and field lines?

 

 

 

 

The magnetic field is an abstract entity that describes the influence of magnetic forces in a region. Magnetic field lines are a visual tool used to represent magnetic fields. They describe the direction of the magnetic force on a north monopole at any given position.

Does magnetic lines of force pass through vacuum?

Do not pass through vacuum.

Can an electromagnetic field exist in a vacuum?

Electromagnetic fields can be produced in a vacuum, but they cannot be produced by a vacuum. Electromagnetic fields can only be produced by accelerating charges, so matter is required.

What materials can magnetic force not travel through?

Can Magnetism Pass Through Everything? The magnetic force (or magnetism) can pass through thin sheets of non-magnetic objects such as paper, glass or wood. However, if the magnet is too weak and the material is too thick, the magnetic force may not be able to pass through.

What does a magnetic force travel through?

Magnetic-field lines pass through cardboard, air, and certain other materials, depending on whether they’re permeable or nonpermeable. Test different materials to see which gather magnetic lines of force and act as magnetic shields, and which allow magnetic lines of force to pass through them.

What are hard magnetic materials?

Hard magnets, also referred to as permanent magnets, are magnetic materials that retain their magnetism after being magnetised. Practically, this means materials that have an intrinsic coercivity of greater than ~10kAm-1. It is believed that permanent magnets have been used for compasses by the Chinese since ~2500BC.

What is soft and hard magnetic material?

Soft magnetic materials are those materials which have a smaller area enclosed by their Hysteresis loop. Hard magnetic materials are those materials which have a Larger area enclosed by their Hysteresis loop. 2. They have low remnant magnetization. They have high remnant magnetization.

Which magnet will produce the strongest force?

The magnetic field generated by any magnet is always strongest at either pole. The magnetic force is equally as strong at both the north and south pole.

Can magnets be harmful?

Generally speaking, magnets below 3000 Gauss (magnetic field unit) are basically harmless to the human body, while magnets with magnetic field strength above 3000 Gauss are harmful to the human body. Although some magnets are harmful to humans, this negative effect is also negligible
