Magnetism - Cobb Learning
... Making Magnets • You can make a magnet from something made of iron, cobalt, or nickel. You just need to line up the domains. • You can magnetize an iron nail by dragging a magnet down it many times (in one direction) • The domains in the nail line up with the magnetic field of the magnet. So, the d ...

... Newton’s First Law of Motion • According to Newton’s first law of motion, the state of motion of an object does not change as long as the net force acting on the object is __________. • Unless an unbalanced force acts, an object at __________ remains at ________, and an object in _________ remains i ...

Experiment 10 Magnetic Fields and Induction
... stick, power supply and resistor. Theory: When an electric charge is moving, it generates a magnetic field in the space. Since a current is a continuous flow of moving charges, it will generate a magnetic field around it. The magnetic field of a current element is given by Biot-Savart Law: dB = µo / ...

... Problem 43: A bar magnet is released above a circular loop of wire as shown, and falls through the loop. The loop is held fixed. A Bird’s eye view (looking at the situation from directly above) is also provided. In class, we discussed the case when the magnet was falling, approaching the loop from ...

Friction Problems ACTIVITY 1: Cut out the problem and the steps
... 4. A child’s wagon of mass 20kg is rolling across the grass with initial speed of 10m/s. The force of friction slows it to a stop in 5s. What is the force of rolling friction between the wheels of the wagon and the grass? 5. Rather than taking the stairs, Martin gets from the second floor of his hou ...
