2)
the magnetic froce , F = q * v * B * sin(theta)
when theta = 90 degree
the magnetic force is maximum
so, the magnetic force depends on thye component of the particle's velocity that is perpendicular to the feild
the correct option is E)
statements concerning permanent magnets is false? The north pole of a permanent magnets is attracted to...

Which o Mbgenetle meld lines alwnys st at a North and end at a south pole the following statements are true? Magnetic field lines always start at a North and end at a South pole. A charged particle moving parallel to the magnetic field will not be affected by it. 수1 The force on a moving charge is perpendicular to both the field and its velocity. When placing a dipole magnet into a magnetic field, it will be accelerated perpendicular...

A positively charged particle is moving upward in the space between the North Pole of one magnet and the south of another magnet. Draw a diagram showing the magnets, field lines, particle velocity vector and force vector. Also, state the direction of the force, since your diagram may be unclear.
T//F with concept explanations True or false: Clearly write whether the statement is true or false in the blank. Write a brief explanation for the reasoning used to arrive at your answer in the space provided, 1 point each. 1) A bar magnet is surrounded by a magnetic field. The field lines flow from the bar magnet's north pole to its south pole Answer 2) A compass needle points toward the Earth's North Pole at the Artic. The compass needle...
Which of the following about the earth's magnetic properties is true? a. The north pole of the earth's fictitious magnet lies beneath the north geographic pole. b. The earth's magnetic field lines end at the south geographic pole. c. The earth's magnetic field lines originate from the north geographic pole. d. The compass needle points to the earth's north geographic pole. e. The earth's magnetic field lines point to the geographic south.
5) Hold a magnaprobe above the magnet and follow the lines of magnetism around from one pole to another. Observe the compass dial as you move along the line of magnetism. What is the shape of the magnetic field above the magnet? 6) Place the north end of a bar magnet distanced from the south end of another bar magnet. (as shown below) Place a piece of plastic over the two magnets and sprinkle iron filings in the region between...
1. The stack of magnets works as one big bar magnet. Do the poles change when you divide the magnet into pieces? 2. In step 3 of the experiment, do both sides of the magnet attract the metal surface? Explain how a single magnet can repel the rest of the stack, but still stick to the other surface. 3. How does the magnet attract something that is originally non?magnetic? 1. Describe the direction of the compass needle as you moved...

Considering our discussion of magnetic fields, how is it that the north pole of a compass needle points toward the earth's geographical North Pole! affect the position of a compass needle? pencil were removed while the ring magnets were positioned in each trial of step 6? 2. If the earth is such a large magnet how can the magnetic field of such a small bar magnet 3. Can two different magnetic field lines ever cross each other? Why of...
A metal ring 4.90 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. These magnets produce an initial uniform field of 1.12 T between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.290 T/s Part A What is the magnitude of the electric field induced in the ring?
