i thin magnetic force cant work in air
You can use a device that detects magnetism. A compass needle may suffice.
Magnetic flux through a loop is just a measurement of the strength of the magnetic field passing through the loop, and since magnetic field strength is directly related to magnetic force, magnetic force is directly related to the magnetic flux passing through the loop.
Magnets have magnetic force in them, obviously, to attract or repel magnetic materials. The materials could not be attracted without the magnetic force because the magnet forces the magnetic material towards it.
Magnetic force is the force exerted on a charged particle moving through a magnetic field. The strength and direction of the force depend on the charge of the particle, its velocity, and the strength and orientation of the magnetic field.
Materials that allow the magnetic force to pass through are known as ferromagnetic materials, such as iron, nickel, and cobalt. These materials have unpaired electrons that align in the presence of a magnetic field, creating a magnetic domain that can conduct magnetic force. Other materials like steel and certain alloys can also exhibit magnetic properties and allow the magnetic force to pass through to varying degrees.
Electromagnets produce a magnetic force when an electric current passes through them. This force is the result of the interaction between the magnetic field generated by the current and any nearby magnetic materials or other electromagnets.
Magnetic force is produced by moving electric charges. When electrons move through a conductor, they create a magnetic field around the conductor. This is known as electromagnetism and is the basis for the generation of magnetic force.
Magnetic force occurs when an electric charge is in motion. When a charged particle moves through a magnetic field, it experiences a magnetic force that can cause it to change direction. This force is the basis for the operation of devices such as electric motors and generators.
No of lines of force can pass through the unit area of magnetic field
Electromagnetic force is produced by the interaction of electric charges and magnetic fields. When a charged particle moves through a magnetic field, it experiences a force perpendicular to its velocity and the magnetic field lines. This force is the electromagnetic force.
The magnetic force in an electromagnet is created by the flow of electric current through a coil of wire, which generates a magnetic field around the coil.
Yes. Magnetic lines of force penetrate paper with little to no difficulty.
