Verified Solutions 2024/2025
1. Line of force - ANS -Direction a hypothetical "free north pole" would travel
in the field. Otherwise known as a field line.
2. Motor effect - ANS -Effect in which a current in a magnetic field
experiences a force.
3. Fleming's left-hand rule - ANS -Way of working out the directions involved
in the motor effect.
4. Magnetic flux density - ANS -Force per unit length per unit current on a
conductor perpendicular to the field lines. Often referred to as the strength
of the magnetic field.
,5. Couple - ANS -Pair of forces in opposite directions that try to turn an
object. Acts on the coil of a motor.
6. Thermionic - ANS -Property of a material that means that when it gets hot,
it emits electrons.
7. Cyclotron - ANS -Spiral particle accelerator.
8. Frequency - ANS -Number of rotations per second, given by 1/T.
9. Mass spectrometer - ANS -Device that separates a constituent of a
substance by their masses.
10.Ion - ANS -Charged atom.
, 11.Velocity selector - ANS -Component that uses an opposing electric and
magnetic field to ensure all particles going straight through have the same
speed and direction.
12.Vacuum - ANS -Space where (nearly) all particles have been removed
(evacuated).
13.Electromotive force - ANS -Force on electrons that tries to push them
along. Known as the emf.
14.Electromagnetic induction - ANS -Phenomenon in which a changing
magnetic field, relative to a wire, will produce an emf.
15.Fleming's right-hand rule - ANS -Also known as the dynamo rule. Works out
directions involved in electromagnetic induction.
16.Solenoid - ANS -Electrical coil.
