Answer:
Using your right-hand: point your index finger in the direction of the charge's velocity, v, (recall conventional current). Point your middle finger in the direction of the magnetic field, B. Your thumb now points in the direction of the magnetic force, F.
Cheers!
Answer:
Movement of Electrons in opposite direction of the rotation of the pickup coil leads to the direction of Electrical energy ( Alternating current ).
Explanation:
For a Generator to generate electricity, Electrons that is found in the rotating coil of the Generator will experience some sort of force that makes them to start moving in a direction that is perpendicular to the direction of the rotating/pickup coil found in the Generator.
The conversion of mechanical energy (Rotation of the pickup coil ) to electrical energy takes place in the Generator
The generator makes an alternating current because electrons move in opposite direction of the rotating coil
In other to generate a Direct current using a generator we have to replace the slip rings with commutator.

To solve this problem we will apply Coulomb's law. For which it tells us that if the charges are constant, the relationship between two forces is equivalent to the inverse of its squared distance. Mathematically this expression can be derived from the Coulomb equation for force:
Here,
k = Coulomb's constant
q = Charge
r = Distance
Under the considerations of the statement we have to
Now replacing,
Answer:
In a nutshell, a scientific law predicts what happens while other laws devised by people usually proposes why certain things happen.
Explanation:
A scientific law is one that predicts the results of certain initial conditions. In order words, it predicts what will happen when certain conditions are fulfilled. A very good example is Newton's 3 laws of motion where like the third law which says to every action, there is an equal and opposite reaction or like in the first law which says a body at rest will remain at rest unless it is acted upon by an external force.
Whereas, other laws devised by people usually provides the most logical explanation as to why things happen the way they do. For example explaining why some children develop certain peculiar health issues when they are newly born.
