Electromagnetic crane is one of the favorite science projects for children. There are many ways to build this model, here we are showing a model which can move in a circular fashion once it is made. Once the model is made it can be tested by changing different parameters like number of turns in the coil, variation in voltage ( more batteries or eliminator can be used). Check for the magnetic field being created near the coil using a compass. It is a recommended project for grade 7 students for understanding Effects of electric current.
