CBSE Class 12-science Physics Magnetic Field
- 01. A thin ring of radius R metre has charge q coulomb uniformly spread on it. The ring rotates about its axis with a constant frequency f revolution/s. The value of magnetic field in tesla at the centre of the ring is
- how bar magnet is equivalent to solenoid
-
answer
- Two small bar magnet are placed in a line at certain distance d apart if the length of each magnet is negligible comapared to d the force between them is inversely proportional to
-
Calculate torque and force acting on the current carrying loop.
-
pls solve
- Why can't the south pole of the magnetic needle deflect in Ampere swimming Rule??
-
Find the magnitude and direction
- A wire of length l is bent in the form of a circular loop with a no of turns and is suspended in a magnetic field of intensity B. Find the expression for the maximum torque produced on the circular loop when a current I is passed through it.
- MUST EVERY MAGNETIC CONFIGURATION HAVE NORTH POLE AND SOUTH POLE AND CAN WE THINK OF MAGNETIC FIELD CONFIGURATION WITH THREE POLES ?
