Answer:
r= 3.2 cm
Explanation:
Given that
I= 8.7 A
B= 5.4 x 10⁻⁵ T
μo=1.25664 x 10⁻⁶
We know that magnetic filed in wire at a distance r given as


By putting the values

r=0.032 m
r= 3.2 cm
Answer:
BA
0

Explanation:
B = Magnetic field
A = Area
= Angle
t = Time taken
Before rotation the magnetic flux is given by

Magnetic flux is BA
After rotation the magnetic flux is given by

The magnetic flux is 0
Magnitude of emf is given by

The magnitude of the average emf induced in the entire coil is 
Answer:
For example, 1300 with a bar placed over the first 0 would have three significant figures (with the bar indicating that the number is precise to the nearest ten).
