A study of the anisotropic effects of superconducting MgB2 was performed. The analysis was performed using electron spin resonance (ESR) and magnetization data. It was observed that conduction ESR (CESR) existed in normal and superconducting states of fine powders of MgB2. The Pauli susceptibility was found to be 2.0×10-5 emu/mole and the spin relaxation rate was found to be anomalous temperature dependent. The CESR measurements and magnetization data proved the anisotropic nature of the superconductor with an uppercritical field. The upper critical field was between 2 and 16 T for CESR and between 6-9 for magnetization data.
