magnetic forces are used in magnetic poles
The Alfven number is a dimensionless parameter used in plasma physics to characterize the behavior of magnetized plasmas. It compares the inertial forces of a plasma to the magnetic forces acting on it, providing insight into the stability and dynamics of the plasma. Mathematically, it is defined as the ratio of the plasma's flow velocity to the Alfven velocity, which is the speed at which magnetic waves propagate through the medium. High Alfven numbers indicate strong inertial effects relative to magnetic forces, while low values suggest magnetic forces dominate.
The Lorentz force, in electromagnetism, is the effect of electric and magnetic forces which act on a point charge moving through electric and magnetic fields.The Lorentz force can be found in scientific apparatus such as particle accelerators, mass spectrometers and magnetrons. More day-to-day equipment are electric motors, loudspeakers and electrical generators.
Beats me. But since there ARE no magnetic lines of force, don't worry about it.
Magnetic field lines do not intersect each other because each point in space can have only one direction of the magnetic field. If two lines were to intersect, it would imply that the magnetic field has two different directions at that point, which is impossible. This property ensures that the magnetic field is well-defined and consistent throughout the space it occupies. Additionally, intersections would suggest conflicting magnetic forces, which cannot physically occur.

In both, opposites attract.

Those include electrical forces, magnetic forces, and gravitation.
Electrical and magnetic forces are non-contact forces because they can act over a distance without the need for direct physical contact between the objects. These forces are mediated by electric and magnetic fields, which can interact with charged particles or magnetic materials without requiring direct touch.
Any force that causes motion or displacement in an object can do work on that object. Examples include gravitational forces, electrical forces, and magnetic forces. Work is calculated as the force applied to an object multiplied by the distance the object moves in the direction of the force.

Electric and Magnetic Forces
mainly positive and negative charges
Electric forces are caused by the attraction or repulsion of electric charges, while magnetic forces are caused by the motion of electric charges.
Gravity, electrical force, magnetic force. These can act with direct touch. "False" forces which are dependent on the observer's motion, such as centrifugal force and g forces are also sometimes considered as non-contact There are also some nuclear forces, but they are not normally observed, and electrical and magnetic forces are really two sides of the same coin.
A roller coaster can accelerate by using gravity, propulsion systems, or magnetic forces. Gravity pulls the coaster down slopes, propulsion systems like motors or launch systems provide additional speed, and magnetic forces can propel the coaster forward using magnetic fields.
