Answer:
Now here first thing…. You never provided with any diagram….! So I will try and explain the Law and at the same time will try and provide with diagram explanation as and were required. If my explanation gets complex, then please feel free to interact and ask as many question or clarification from me.
Explanation:
Now what we are speaking here is the phenomenon of induction of current when it is allowed to pass through a solenoid. This is best explained making use of the Faradays law of induction. This type of current is also termed as a type of generated electricity.
On moving a magnet through the electric field, some amount of electric current is always induced in the wire that cuts the magnetic lines f forces. Such type of voltage is also termed as induced voltage and can easily be seen as deflection in the voltmeter that is connected across the circuit.
So if you connect a sensitive loop and a ammeter across the circuit, you will also notice it getting deflected. This deflection is due to the electric current present in the circuit. This deflection is only noticed if the magnet is moved either in the up or in the down direction.
So if we consider the case as I have shown the diagram, then the magnetic lines of forces are perpendicular to the direction of flow of current. And the magnetic lines of forces are already marked with arrows in the figure. So the direction in which the current flows will be opposite to the direction of the marked magnetic lines of forces.
So I hope this explanation helps you….
The correct answer is:
B. Magnetic field.
The magnetic field label belongs in the area marked X.
