Please solve a and b using college algebra physics and show equations used to solve

1) A small 100.0-turn coil has a radius of 0.0500m and is in a magnetic field that goes into the page (see diagram). The magnetic field is created by a solenoid (not pictured) that has 1,650 turns and is 0.900 m long. Initially 2.00 amps flow through the solenoid to make the pictured magnetic field, but over 3.25 seconds the current increases to 8.90A. Find a) the magnitude of B the induced Emf on the small coil b) the direction current will flow through the coil. Small coil
