(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) Describe the three basic interactions between electricity and magnetism.
Volcanic and other such activity at the mid-Athletic ridge extrudes material to fill the gap between separating tectonic plates associated with continental drift. The magnetization of rocks is found to reverse in a coordinated manner with distance from the ridge. What does this imply about the Earth's magnetic field and how could the knowledge of the spreading rate he used to give its historical record?
Earth’s magnetic field lines are not parallel to its surface except in certain places: they actually 44dip” downward at some angle to the ground. (An ordinary compass does not show this.) (a) At what places on Earth would the magnetic dip” be the greatest? (b) Where on Earth would the dip be zero?
The quantity B ds in Amperes law is called magnetic circulation. Figures 30.10 and 30.13 slum paths around which the magnetic circulation is evaluated. Each of these paths encloses an area. What is the magnetic flux through each area? Explain your answer.
A transmission line strung 7.0 m above the ground carries a current of 500 A. What is the magnetic field on the ground directly below the wire? Compare your' answer with the magnetic field of Earth.
Neurons in our bodies carry weak currents that produce detectable magnetic fields. A technique called magnetoencephalography, or MEG, is used to study electrical activity in the brain using this concept This technique is capable of detecting magnetic fields as weak as 1.0 1015 T. Model the neuron as a long wire carrying a current and find the current it must carry to produce a field of this magnitude at a distance of 4.0 cm from the neuron.
A wire carrying a 30.0-A current passes between the poles of a strong magnet that is perpendicular to its field and experiences a 2.16-N force on the 4.00 cm of wire in tire field. What is the average field strength?
If a current flows in the Satellite Tether shown in Figure 23.12, use Faraday’s law, Lenz'S law, and RHRl to show that there is a magnetic force on the rather in the direction opposite to its velocity.
A 25-cm nod moves at 5.0 m/s in a plane perpendicular to a magnetic field of strength 0.25 T. The rod, velocity vector, and magnetic field vector are mutually perpendicular, as indicated in tire accompanying figure. Calculate (a) the magnetic force on an electron in tire rod, (b) the electric field in the rod, and (c) the potential difference between the ends of the rod. (d) What is the speed of the rod if the potential difference is 1.0 V?
what creates a magnetic field? how does this work in a magnet to create a strong magnetic field that ca attract or repel metals?
1. Explain briefly how Lenz’s law is said to follow the Law of conservation of energy (that explains why there has to be an opposing magnetic field) 2. Why do you think, we need to study the processes, principles and laws in electricity production and distribution?
BQ. What is magnetism? How many types of magnets are there? Describe them. Derive any two equations you learned from the topic of magnetism and explain meaning of them. (+ 5)
