Faraday’s Law 1 Given: F i n d : A i 25 ? I s A dt di / 5 . 3 / cm a 17 8 . 4 R cm d 18 An infinite wire with 25 A of current moving upward is decreasing at a rate of 3.5 A/s at a given instant. A square loop with dimensions of 17 cm by 17 cm is to the left of the wire and has a resistance of 4.8 . The right edge of the loop is 18 cm from the wire: Find the current induced in the square loop at that instant. (If the current is CW enter your answer as a negative number and if the current is CCW enter your answer as a positive number.) Solutions a.) To find I we can use the following formula: enc i l d B 0 enc i l d B 0  enc i r B 0 2
