Hey there,
The answer to your question is:
Option A
A) The wiring contained a short circuit, so the reduced resistance caused an increase in current.

Answer: Use the Right -hand Rule to find the direction of the magnetic field.
Explanation: A magnetic force only occur, in a magnetic field, when a particle is moving perpendicularly relative to the magnetic field. So, all three quantities are perpendicular among themselves.
The Right-Hand Rule apply for the positive charges moving in conventional current. If the moving charge is negative, the velocity must be reversed.
Right-Hand Rule determines the direction of any or all of the three and it is as follows: With you right hand, point your index finger in the direction of the velocity, your middle finger in the direction of the magnetic field and your thumb will be pointing in the direction of the magnetic force.
Another way of using the rule is when there is a current carrying wire:
The fingers of your right hand will curl into a half circle around the wire, they will point in the direction of the field. The thumb will point in the direction of the conventional current.
Transpiration is the evaporation of water from plants. This occurs when water drawn from the roots is brought up the leaves (as it usually should), and, because of the outside heat, it vaporizes and exits via the pores found on the underside of the leaves.
It is a very reactive metal with 11 protons ,12 neutrons, 11 electrons, and 1 valence electron
