1) Induced emf in a coil depends on a) Relative motion of magnet b) Relative motion of coil c) Both d) None 2) When is passed through coil is there magnet a a (changing/unchanging) magnetic flux through the coil that induces an electromotive force(emf) in the coil; the incoming flux is (equal /not equal)to the outgoing flux. 3) While a magnet is moved toward the end of a solenoid, a voltage difference is induced between the two ends of the...
can you explain why the bulb does not shine when the coil isnt
moving horizontally or when the coil is moving vertically?
4. Select Stop" to stop the vertical motion. Move the coil horizontally until all the coil is out of the magnetic field, then stop the motion of the coil. Rotate the coil another 90° so that it is now viewed edge-on when you are in "Viewing from Side" view. 5. Move the coil horizontally and then stop it...
You want to use the idea of electromagnetic induction to make the bulb in your small flashlight glow; it glows when the potential difference across it is 1.5 VV. You have a small bar magnet and a coil with 100 turns, each with area 2.6×10−4m22.6×10−4m2. The magnitude of the B⃗ B→ field at the front of the bar magnet's north pole is 4.0×10−2 T4.0×10−2 T and reaches 0 TT when it is about 4.0 cmcm away from the pole. With...
Moving a magnet in and out of a coil will make the needle on a galvanometer move to each side. a) explain what is happening in terms of magnetic induction. b) what would it take to induce an emf that stays positive, or that stays negative? is it possible? c) how can you get the largest possible deflection of the needle? explain what you do in terms of the magnetic field of the magnet, and the induced emf.
1. OBSERVATIONAL EXPERIMENT: HOW TO INDUCE A CURRENT IN A COIL NOT CONNECTED TO A BATTERY The goal of this experiment is to observe 2 sets of videos to find a pattern for the conditions under which there is a current through a coil of wire that is not connected to a battery. Available equipment: Computer with internet connection a) First, make sure you know what a galvanometer is. A galvanometer is a device that registers electric current through it....
You are given 13.0 m of thin wire. You form the wire into a circular coil with 70 turns. If this coil is placed with its axis parallel to a 0.12 T magnetic field, what is the flux through the coil? Express your answer with the appropriate units.
You are given 13.0 m of thin wire. You form the wire into a circular coil with 60 turns. Part A If this coil is placed with its axis parallel to a 0.19 T magnetic field, what is the flux through the coil? Express your answer with the appropriate units.
Accessory Unit Arm Magnet Assembly Main Unit 121 のの のの Equipment: 1 current-carrying wire set-up 1 power supply 1 ammeter Investigation 3: Relationship between force and angle between the current through a current-carrying wire and the magnetic field In this section we will explore the relationship between the force on a current-carrying wire and the angle between the current and the magnetic field. a. Predict the dependence of the force on the angle between the current and the magnetic field....
You are given a kit to build a basic speaker. Inside there is a wire, a magnet, a couple of small sticks, and a cup. Explain, in a paragraph or so, how a speaker would work with the given materials.
Please give step by step solution so I can understand and
follow along.
I will rate, thank you.
3. A tungsten light bulb filament (see the figure at the right) is a coil of a coil to reduce evaporative losses (the light bulb itself contains an inert gas to also reduce evaporative losses and to also reduce the operating temperature of the filament. The inert gas is usually argon). The uncoiled diameter of the filament is 47 μm and the...
