What is the magnetic field strength inside the gas cloud?

Radio astronomers detect electromagnetic radiation at 44.0 MHz from an interstellar gas cloud. They suspect this radiation is emitted by electrons spiraling in a magnetic field.

B= 2 *(pi)* (mass of electron)* (frequency in Hz) / (charge of electron)



mass of electron= 9.11*10^-31

charge of electron= 1.6*10^-19
