General Physics 2 w/o calc
Now suppose that the battery is removed and replaced with an ammeter. No current will flow through the wire because there is no energy source. Consider what will happen when a barmagnet is pushed toward the coil as shown in the figure below. When the coil "feels" the changing magnetic field caused by the approach of the bar magnet, it will thereby become energized; a current will begin to flow through it, and the ammeter will register that current. This...
What is the direction of the induced magnetic field in the coil when the bar magnet is moving...
A coil is suspended around an axis which is colinear with the axis of a bar magnet.The coil is connected to a resistor with ends labeled “a” and “b”. The bar magnet moves from left to right with North and South poles labeled as in the figure. UseLenz’s law to answer the following question concerning the direction of induced currents and magnetic fields.What is the direction of the induced magnetic field in the coil when the bar magnet ismoving from...

2. The south pole of a bar magnet is brought close to a 250s-turn/m, 60-cm long copper solenoid with a radius of 7 cm. The wire has a cross-sectional area of 1.33 x 105 m² and is being kept at 25°C. Copper wire has a resistivity of 1.72 x 10% Om at 20°C and a temperature coefficient of resistivity of 3.9 x 10C!. If there is an induced current of 3 A after 0.2 s, what is the strength and...

When you drop a magnet (North Pole first) through a large coil and measure the induced voltage over time, you will notice that the induced voltage has one peak upward and one peak downward. Explain why this happens. You will also notice that these voltage peaks are not the same magnitude, but the area under the peaks are nearly the same. Which peak is larger, the earlier or the later one? Explain why. What do the areas represent and why are...

You have a magnet that is 2.3cm in diameter and 9cm long. At the north pole of this magnet, the magnetic field is 0.09T. You want to see if you can construct a solenoid with the same dimensions as the bar magnet with the same strength. If you constructed the solenoid out of 18-gauge wire (diameter 1.02mm), how many turns would it take when passing 2.2A through it to create the same magnetic field? Does this seem like a reasonable...
