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

Play/Pause Button: This control toggles the switch, activating or deactivating the circuit and thus the electromagnetic effect.
Reset Setup Button: Resets all variables to their default settings, allowing for a fresh start with each experiment.
Reset Data Button: Clears all data collected in the data logger, preparing the tool for new data capture without previous influence.

About this Simulation

This interactive simulation lets you investigate what makes electromagnets stronger. Adjust the number of coils, switch between iron and plastic rods, change rod size, and vary battery number and strength to observe how many paperclips your electromagnet can pick up. Discover the relationships between each variable and magnetic force.

Learning objectives: Understand how the number of coils affects electromagnet strength | Identify the role of core material and battery power in magnetic force | Predict and test electromagnet performance under different conditions
