Strength of an ElectroMagnet with variables number of coils, material of rod type, iron or plastic, size of rod large or small, number of batteries, battery strength full or low

Number of Coils: Adjust coils around the rod to see their effect on strength.
Rod Material: Compare iron and plastic rods to observe material impact.
Rod Size: Switch between small and large rods to study field strength changes.
Number of Batteries: Test 1–5 batteries to see how current affects magnetism.
Battery Power: Vary levels from low to full and observe the effect.
Circuit Switch: Open/close the circuit to control magnetic activation.

About this Simulation

This interactive simulation models how electromagnet strength changes based on multiple variables including number of coils, rod material (iron or plastic), rod size, number of batteries, and battery condition. Students adjust parameters and measure electromagnet strength using paperclips as indicators.

Learning objectives: Understand how coil number affects electromagnetic strength | Investigate the role of core material in electromagnet performance | Explore how battery quantity and condition influence magnetic force
