Academics

An insulated copper wire is wrapped around an iron nail. The resulting coil of wire consists of 240 turns of wire that cover 1.8 cm of the nail, as shown in the figure . A current of 0.50 A passes through the wire.(Figure 1)

If the ferromagnetic properties of the nail increase the field by a factor of 100, what is the magnetic field strength inside the nail?

Express your answer using two significant figures.
