PH 1120 - Electromagnetic Induction - Lab Report Your Name & Section: Connor Downie B09 Partner’s Name: William MacDowell B09 Date: 12/9/10 1. State the value of the Earth’s magnetic field magnitude that you measured, and comment on the field orientation that you observed at your station. The field values were .0363mT when pointing straight down -.0382mT when pointing straight up So the magnetic field of the earth is equal to .0372mT = .0000372T = .372Gauss 2. Consider the magnetic induction situation when the magnet is rapidly inserted into a coil, held motionless, and then rapidly removed from the coil. Explain briefly the circumstances in this 3-step process that produce an induced EMF, and why their polarities are different. Because magnetic field and current are related, when you apply a magnetic field into a coil, it generates a current a direction perpendicular to the field. When the magnet is removed, it reverses the direction of the current. So the faster that the magnet is
