What is the force between magnetic fields?

The most elementary force between magnets is the magnetic dipole–dipole interaction. If all of the magnetic dipoles that make up two magnets are known then the net force on both magnets can be determined by summing up all these interactions between the dipoles of the first magnet and that of the second.

Is magnetic field Solenoidal?

In physics, the term solenoid refers to a long, thin loop of wire, often wrapped around a metallic core, which produces a magnetic field when an electric current is passed through it. Solenoids are important because they can create controlled magnetic fields and can be used as electromagnets.

Do magnetic fields exert force?

Right Hand Rule: Magnetic fields exert forces on moving charges. This force is one of the most basic known. The direction of the magnetic force on a moving charge is perpendicular to the plane formed by v and B and follows right hand rule–1 (RHR-1) as shown.

Why is magnetic field outside solenoid zero?

The magnetic field lines exist outside the solenoid, but the number of field lines per unit area (flux) outside the solenoid is much less compared to the number of lines per unit area (flux) inside the solenoid. Hence the magnetic field outside is so weak that it is considered to be practically zero.

Do magnetic forces only act on moving particles?

Magnetic force acts only on moving charges and not on stationary charges. Why? – Quora. , Ardent student of electromagnetism. Because the magnetic field acts perpendicular to a charges instantaneous direction of motion (at right angles to its motion).

Is magnetic force a deflecting force?

A positive charge, top, moving perpendicularly through a magnetic field is deflected. The right-hand rule, bottom, predicts the direction in which the positive charge will be deflected. A similar left-hand rule predicts the deflection of negative charges.
