Answer:
Should place the current perpendicular to the magnetic field
Explanation:
The magnetic force exerted on a current-carrying wire is given by
where
I is the current in the wire
L is the length of the wire
B is the magnetic field
is the angle between the direction of the wire and the magnetic field
As we see from the formula, the magnetic force is maximum when
which means
So, when the current in the wire and the magnetic field are perpendicular to each other.
Answer:
Induced emf will be equal to 51.76 volt
Explanation:
We have given number of turns N = 80
Dimension of rectangular coil is 25 cm by 40 cm
So area of rectangular coil
Change in magnetic
Change in time is given dt = 0.08 sec
Induced emf is given by
So induced emf will be equal to 51.76 volt
