It is repulsive if the currents are in opposite directions. Adjust the length of the pendulum so that the free-swinging magnet will plz i will mark best as brainleist. Coulomb's law, or Coulomb's inverse-square law, is an experimental law of physics that quantifies the amount of force between two stationary, electrically charged particles. The first force would be the repulsion one expects between two magnets with the same poles facing one another. Write 5 “fact” sentences and 5 “opinion” sentences Explain why. The data from the demonstration can also be used to calculate the universal gravitational constant G. Photo courtesy Clive Grainger it and which are repelling it. or in the starting position of the pendulum may cause the pendulum to develop When you place the north pole of one magnet near the south pole of another magnet, they are attracted to one another. motion of the two magnets. If taught efficiently, a student should do well on the End-of-Level (CRT) tests. A magnet produces a magnetic field around itself. Have the students see if they can make each of the magnets appear to “float it from the side of a wooden table using a piece of tape. By exploring variables, students come to understand the features that affect the strength of electromagnets. The force between two wires, each of which carries a current, can be understood from the interaction of one of the currents with the magnetic field produced by the other current. Resources and services for Utah Higher Education faculty and students such as Canvas and collegEmedia. Liquids that have a LOW viscosity flow quickly (ie.
