inducing current

who induced a current in a circuit by moving a wire through a magnetic field

• michael farady

• my mom

• lenz

• van gogh

when both wire and magnetic field are stationary, I=?

• 0

• 90

• 45

• 10

what does the blue arrow represents?

• current (I)

• magnetic field (B)

• velocity (v)

• emf

• 0,90

• 90,0

• 0,180=0

• 118,90

• I=MAX

  theta=MAX

• I=0

  theta=90

• I=MAX

  theta=90

• I=0

  theta=0

an electric current can be generated in a wire in a circuit when at least part of the wire.....?

• is rotating

• is in contact with a magnet

• moves through and cuts magnetic field lines

• has been formed into a coiled shape

who made the same discovery as michael faraday

• james maxwell

• joseph henry

• joseph ben

• james charles

EMF is measured in...?

how is current induced?

• it requires a source of energy (EX. battery)

• charges flow from a lower to higher potential difference

• charges flow from a higher to lower potential difference

• the potential difference given to the charges by a battery is called EMF

EMF is?

• a force

• a potential difference

• magnetic field

• current
