Answer [2]: In order to experience a force the electron has to be moving; if it is a rest it will experience no force. As a result, a magnetic field cannot set the electron into motion (Newton's 1st Law). ... Answer [3]: (a) A charged particle in an electric field experiences a force (F = qE) and so its motion will change ...

The charge must be moving. No magnetic force acts on a stationary charge. ... The magnetic field B is a vector, and its direction is direction is along the zero-force axis ... A charged particle in a constant magnetic field will do uniform circular ... of the magnetic force exerted on the wire, largest to smallest. ...

I'm confused about what you mean by the tangent of the field line and so on. The field is a vector field and everywhere at each point in space there's just one vector which has a specific direction and magnitude indicative of the force and its direction due to the force field at that point in space.

The magnetic field is at right angles to the direction of the electron and is ... magnitude at right angles to its path regardless of its direction. ... The largest possible path had a radius of about 50 mm. ... When the magnetic field B is switched on, what force will be exerted on one moving charge carrier? ...

(b) What is the smallest possible magnitude of the acceleration of the electron due to the magnetic field? (c) If the actual acceleration of the electron is 1 of the largest magnitude found in part (a), ... (a) The force on the electron due to the magnetic field is F = (-e)v B. Since F = ma, we can write an equation for...

c- both (a) and (b). 16. A moving proton a- is actually an electric current. b- produces an electric field. c- produces a magnetic field. d- all of the above. 17. The force on an electron moving in a field will be the largest when its direction is a- the same as the magnetic field direction.

For example, the horse-shoe shape is very commonly used in magnetic separators because its lines of force are mostly at the open end of the horse-shoe, and this helps in the separation of ferrous materials. A piece of iron placed within the effective range of the magnetic field will, in turn become magnetized.
