Two technicians are discussing magnetic coils. technician a says that the magnetic force can be increased by increasing the number of windings in the coil. technician b says that won't because adding windings also increases the length of the wire, so current flow will go down and the magnetic strength will be the same. who is correct.
Answers: 1
is the magnetic permeability, 
is the number of windings, 
is the current in the coil,

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
