This electromagnet consists of 2 large copper wound bobbins placed around a large u-shaped soft iron core. Pair this magnet with a set of spring scales to measure the relationship between input voltage and force. A great way to study remanence (magnetization left behind after a magnetic field has been removed), the large iron core of this electromagnet helps to enhance this effect.

Iron core diameter: 11 mm

Length of copper wound bobbins part: 45mm

Total length with hanger: 120 mm
