A coil of radius r is made of N circular loops. It is connected to a battery of known emf and internal resistance. The coil produces a magnetic field whose magnitude at the center of the coil is B→.What physical quantities can you determine using this information? (2):The resistance in the circuit / the magnetic dipole moment of the coil / the current in the circuit / the Earth's magentic fieldFrom the two, determine their physical quantities?
