A convenient, well-made solenoid for investigating the magnetic field of a coil and for the current balance experiment. The clear acrylic former and the large diameter (90mm) allow items placed inside the coil to be easily seen
Balance kit, package includes an air core solenoid and a current balance for demonstrating and measuring the small force experienced by a conductor carrying an electric current in a magnetic field, one half of the current balance is placed inside the solenoid
