Magnetic Force on moving charges   Direction     1) Thumb - direction of moving charge (Left - Right +)   3) 4 fingers - Flux Direction   4) Palm - direction of PUSH (force) on charge   Ex 1) Direction?     Left     Out of page       Force up           Force into page     Answer: Into or Out of the page?       Out of Page     Magnetic force is maximum when charge moves perpendicular to field (Charge shot up)     Magnetic force = 0 when charge moves ...   ... parallel to field     Force on a charge 1. Fmag = Bqvsinq  q is angle between charge v and field 90 max, 0 degrees F = 0   B - flux density of magnetic field (strength) Teslas (T)   q - charge (C)   v - velocity (m/s)           Ex) Charge shot in field, speed and KE not changed. W=0 If perpendicular, charge will move in a circle   Bqv  = mv2/r     Bq  = mv/r     r  = mv/Bq     Page 259) Review Book #2 - #5         2) c   3) d   4) d   5) a   Handout p. 10) 36   Enrichment   Neodymium magnet/TV magnetportal.de School Block YouTube?
