Electric field of a solenoid Prediction: Get a mathematical expression for the magnitude of the magnetic field as a function of the distance along the central axis of the solenoid. Also compare the pattern of the solenoid with that of a linear magnet. Prediction method: 1. For the magnetic field equation, start from the equation of the magnetic field generated by a solenoid and transform the angles into linear lengths. 2. For the field patterns, first draw the solenoid and label the current flowing through it. 3. Using the right hand ruler, determine the direction of the magnetic field along the central axis of the solenoid. Which axis of symmetry of a bar magnet corresponds to this central axis? 4. Complete your diagram by drawing the magnetic field lines all around the solenoid. Compare this pattern with that of a ma
