Strength of the external magnetic field
The mass of the conductor
The length of the conductor in the field
The angle the conductor makes with the external magnetic field.

This is simple enough if you remember the formula:

From which it is easy to see that the mass of the conductor has no effect.

Like currents attract
Unlike currents repel
The force is shared between the conductors proportionally to their relative lengths
The force is proportional to the inverse of the distance between them.

Armature
Rotor
Brushes
Split-ring commutator

Simple anatomy of a motor.

Permanent Magnets
Static Electricity
Current Carrying Coils
Electromagnet

All the other three produce a magnetic field which can be used in a motor.

The magnetic field in a galvanometer is radial
The needle rotates until the magnetic force is equalled by a counterbalancing spring
The loops of wire in a galvanometer are connected in parallel
An iron core increases the magnitude of the magnetic force

The loops of wire in a galvanometer are actually connected in series.

The voice coil is physically attached to the magnets
Both magnets are a square shape
The voice coil vibrates side to side as a result of the motor effect
The voice coil is connected to the output of an amplifier

The voice coil is not physically attached to the magnet, but sits between the poles.

(b) is incorrect because there is only one magnet and it is not a square.

(c) is incorrect as the voice coil vibrates in and out, not side to side.

Magnetic Flux
Magnetic Flux Density
EMF
Teslas

Magnetic flux density is the term given to describe the strength of a magnetic field. Teslas are the units.

Lenz's Law
Faraday's Law of Induction
Tesla's AC Theory
Einstein's theory of special relativity

Back EMF
EMF
Eddy Current
Rotational Kinetic Energy

You just need to know the definitions to answer questions 8 and 9.

Electrical to Kinetic Energy
Rotational Kinetic Energy to Electrical Energy
Rotational Kinetic Energy to an Induced EMF
Heat to Electrical Energy

A generator works by moving a current carrying coil inside a magnetic field. This induces a current in the coil, hence converting the rotational kinetic energy of the coil into electrical energy by means of an induced EMF.

Using superconducting wire for transmission
Decreasing the current
Increasing the voltage
Changing the material used for transmission

The trick here is in the use of the word 'definitely.' Superconductors will obviously have smaller losses than regular transmission cables.

Decreasing the current helps because of the formula for power loss in transmission lines:

Increasing the voltage also will help because if you increase the voltage, the current must decrease in accordance with conservation of energy. Hence (c) is essentially the same as (b).

Changing the material MAY work but it depends what material you change to. If it is one with a larger resistance then it will not help at all.

DC generators need to be located close to towns because of the huge losses in transmission
AC electricity can be transformed
DC generators were patented by the Edison General Electric Company
AC generators have a slightly simpler design

In fact, it is DC generators that have slightly simpler designs. DC generators have one commutator whilst AC generators require two slip rings, making them slightly more complicated.

Thomas Edison
Nikola Tesla
Westinghouse
Michael Faraday

Tesla actually produced the first AC generator whilst working for Edison. Edison refused to pay him for it, so he left and the patent on AC generators was taken out by Westinghouse.

Earth Linkage
Transmission Line
Suspension Insulator
On-line Transformer

The current in the secondary coil is larger than that in the primary coil
The output voltage is smaller than the input voltage
The output power is greater than the input power
None of the above

(a) is wrong because it is the voltage in the secondary coil than is larger than that in the primary coil, not the current.

(b) is false as the output voltage is obviously larger than the input voltage in a step-UP transformer.

(c) is incorrect as the output power could not possibly be larger than the input power as a result of the law of conservation of energy.

Therefore, (d) is correct.

Television
Mobile Phone Charger
Christmas Lights
Air Conditioner

A television requires a step-up transformer to power the cathode ray tube.

They are cheaper
They are good transmitters of magnetic flux but poor conductors of electricity
They reduce the amount of heat produced
They are not actually used in transformers

That is the reason why ferrites are used.

Lightbulb
Torch
Christmas Lights
None of the above

All of these devices have some inefficiencies in that some of their power is converted into heat energy.

Insulators in transformers reduce loss due to heat
Nikola Tesla once worked for the Edison General Electric Company
Westinghouse argued with Edison over whether AC or DC electricity was best
All of the above

All of the above statements are true.

The mass of the transformer
The distance between the primary and secondary coils
The type of core used
All of these affect the performance of a transformer

(b) and (c) both affect the performance of a transformer but a transformer's mass has no bearing on its performance.
