A torque magnetometer G.E. type gaussmeter using weak ferromagnetic rotors is described. Such an instrument gives a reading essentially linear with fields up to 100,000 gauss. The actual torques are higher than those obtained with para-or diamagnetic rotors, even at 100,000 gauss. An experimental instrument was built, and found to yield a linear reading up to the highest field available i.e. 25 Kgauss. Author
