The South-Pole of a bar-magnet will repel the South-pole of another bar-magnet. True False
If the Earth were a bar magnet, its magnetic north pole would be located near the geographic North Pole and its magnetic south pole would be located near the geographic South Pole. True False
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...
Find the direction of induced current when the south pole of a bar magnet is moved inward and outward from a current loop. Explain your answer with diagrams on the basis of Lenz’s law.
The North-pole of one bar-magnet will attract with the North-pole of another bar-magnet True False
a
permanent magnet is placed horizontally with the right end being
its South Pole. a conducting loop is pushed to the left towards the
South Pole. the direction of the induced magnetic field due to the
induced current in the loop is
5. A permanent magnet is placed horizontally with the right end being its south pole. A conducting loop is pushed to the left towards the south pole. The direction of the induced magnetic field due to the induced...
1. What is the induced EMF when the south pole end of magnet moves closer to the plane of the coil? When the magnet is stationary what happens to the induced voltage? 2. What happens when the north pole end of the magnet moes all the way through a coil? Explain in detail please
1-A compass is held horizontally. The silver end of the needle
points towards geographic south and the blue end points towards
geographic north. The compass is then brought near one pole of a
horseshoe magnet. The blue end of the compass points towards this
pole. What is the polarity of this pole on the magnet?
2-Two bar magnets are arranged so that the ends face each other
in a line as shown below. At the spot “x”, the north pole...
A bar magnet is held vertically above a horizontal metal ring, with the south pole of the magnet at the top (Figure 22.63). If the magnet is lifted straight up, will current run clockwise or counterclockwise in the ring, as seen from above?
The magnetic field of Earth resembles the field of a bar magnet. The north pole of a compass needle, used for navigation, generally points toward the geographic north pole. Which magnetic pole of the Earth is the compass needle pointing toward?
