Magnetic field lines indicate presence of a magnetic field
When current flows a magnetic field is generated around the flowing electrons.
Note:(a) This magnetic field is also called an electromagnetic field. (b) This magnetic field is the same magnetic field as the field made by a horse shoe magnet

MathThe voltage value times the current value equal the power
Power of electric current is directly proportional to the magnetic field strength.
B is the symbol for field strength
B can have units of Newton per cm
VocabularyInductor
Voltage - measured in volts
Current- measured in Amperes
Power- measured in volt-Amperes
Note 1 Watt equals 1 volt-Ampere
