Electrons are heated locally and temporally in a uniform magnetoplasma by applying a short current pulse to a loop antenna. The resultant heat pulse, satisfying electron MHD conditions ({omega}{sub {ital ce}}{sup {minus}1}{lt}{Delta}{ital t}{lt}{omega}{sub {ital ci}}{sup {minus}1}), generates helicity due to twisting of field lines by diamagnetic drifts. Heat convection and diffusion cool the pulse, which reduces its propagation to zero. The stationary temperature profile decays by cross-field transport conserving volume-integrated heat. {copyright} {ital 1996 The American Physical Society.}
