Metal halide perovskites have shown great potential for both light‐absorbing and light‐emitting devices. It is demonstrated that the presence of a low‐magnetic field decreases dramatically the photoluminescence of CsPbBr 3 . This is found to be due to a decrease in charge separated state lifetime. The effect is fully reversible, and can be exploited for simple and remote modulation of the output of light‐emitting devices.
