### Can repelling Magnetic fields generate EMF

Posted:

**Mon Aug 03, 2015 11:03 am**Hi Everyone,

I have 4 scenarios in question . Will The EMF(Voltage) magnitude be the same in all of the scenarios?

- the difference between the two photos are in the polls: one repel one attract .

- i understand that the current(amps) will change between scenario 1,2 and 3,4 due to the wire length assuming same gauge

1) Photo 1: d1 = 1cm, d2=20cm, wire length=240cm, Wire Exposed to field=80cm, each magnet is 1 Tesla(at surface), coil moves at 6meter/second

2) Photo 1: d1 = 1cm, d2=10cm, wire length=200cm, Wire Exposed to field=80cm, each magnet is 1 Tesla(at surface), coil moves at 6meter/second

3) Photo 2: d1 = 1cm, d2=20cm, wire length=240cm, Wire Exposed to field=80cm, each magnet is 1 Tesla(at surface), coil moves at 6meter/second

4) Photo 2: d1 = 1cm, d2=10cm, wire length=200cm, Wire Exposed to field=80cm, each magnet is 1 Tesla(at surface), coil moves at 6meter/second
