%X We have designed and tested compact magnetic B and dB/dt sensors suitable for geophysical operation through monitoring the current and voltage induced in a test conductor within the sensor. Laboratory and field tests confirm that a 50 cm long sensor of mass less than 1 kg can be constructed with noise levels between 1 pT and 10 fT per vHertz over the 10 Hz to 100 kHz bandwidth respectively. The sensors are robust, and a rigid 3 component mounting box with accelerometer orientation permits rapid field deployment without the need for levelling
