Cathode ray deflection tube
... A bar magnet can now be held at the side of the tube and you will see that the beam of electrons is deflected up or down depending which way round you hold the magnet. The same thing will happen of course if you use an electromagnet (see Figure 3). Magnetic field at right angles to the paper ...

Electron paramagnetic resonance
Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a technique for studying materials with unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but it is electron spins that are excited instead of the spins of atomic nuclei. EPR spectroscopy is particularly useful for studying metal complexes or organic radicals. EPR was first observed in Kazan State University by Soviet physicist Yevgeny Zavoisky in 1944, and was developed independently at the same time by Brebis Bleaney at the University of Oxford.
