                   Consider a hollow cylinder. The inner radius r1=1 and the

outer radius r2=2. Assume the cylinder has a current of I ampere flowing through it.
a. Derive an expression for the magnetic field in the hollow part of the cylinder i.e.
for rb. Derive an expression for the magnetic field between r1 and r2, i.e. for r1c. Derive an expression for the magnetic field outside the cylinder, i.e. for r>r2.

what are the methods of Methods of producing induced emf
 
 
Hence, the induced emf can be produced by changing the magnetic induction area enclosed by the coil and the orientation of the coil (θ) with respect to the magnetic field and too depends...

the geometric length of a bar magnet is 24cm. the length of the magnet is
 
 
the magnetic length of a magnet is aproximately 6\7 of its geometric length therefore the answer is 20.57cm(approx)

Two manganin wires whose lengths are in the ratio 1:2 and whose resistance are in the ratio 1:2 are connected in series with a battery. What will be the ratio of drift velocities of free...
 
 
The equation used for solving this problem is I=neAv d The current through the two wires are same as they are connected in series connection. Now R = ρl /A => A α l/R => A 1 /A 2 =( l 1 /l...

What is the approximate peak value of alternating current producing four times the heat produced per second by a steady current of 2A in resistor.??? 2.8 A, 4 A, 5.6 A, 8 A
 
 
I rms = 2*I steady (this is given in the question i.e. four times the heat produced) I rms =I max /1.414 Using the above 2 relations we can find out that, I max =2.828 I steady . I max...
