Answer :
the magnetic field strength created at its center is 9.42ms.
What is magnetic field?
A magnetic field is a vector field influence on moving charges and electric current.
We have given a motor inside it. The current I =30 M.
Circular coil having number of tens = 250 .
And the radius of each turn it is = 10 cm= 0.100
So we have to find the magnetic village trained to be at the center of the coil. So we know that the magnetic field
t manipulated and which=250
Current = 30 M.
this value.
After solving this = magnetic field b. It is = 0.094 More accurately it can be written as 9.42.
Made clear by 10^-t3 or magnetic field= 9.42 ms
