The statement is not correct since there is no such thing as a "magnetic charge. There is a hypothetical particle called magnetic monopole but its existence was never observed. A magnetic field is induced by electric currents, permanent magnets, electromagnets, and the smallest moment that induces the magnetic field is a dipole.
Result:
There is no magnetic charge. There is a hypothetical particle called magnetic monopole but its existence was never observed. So the statement is not correct.
