Magnets can attract and repel because of the magnetic fields around the magnet. We then built upon what we observed, and used the knowledge to aide in the magnetization and demagnetization of a paperclip. Im working on a magnetic field lab for physics. 1 Lab # 5: Magnetic Fields Introduction In this lab we examined magnetic field lines through the use of a bar magnet and a compass. PhET. Day 1 Lab 1: Magnets and Magnetic fields . ... Answer: Magnetic flux density (B) = NI / L 2.5 = x 100 x 2 / 0.25 = 0.0031 T.m/A 6. A magnet is a material with poles and a magnetic field created by the configuration of its electrons. The measurement of variations in the Earth’s magnetic field is used to tell the location of something below the Earth’s surface. Whenever a current flows through a wire, a magnetic field is produced in the region around the wire. Day 3. Introduction All magnetic fields arise from the motion of electric charges. Notice how the force/magnetic field lines point away from the magnet’s North pole and toward its South pole. The information we are given are the following equations in the pictures and the data we have collected is: Solenoid: Voltage, distance, and length of solenoid; Coil: Voltage, Distance, and Radius. Theory The magnetic field of Earth resembles the field of a bar magnet. 1 . We need to determine the magnetic field of both a large coil and a solenoid which I need help doing. For current flowing through multiple wires, such as a section of a rectangular coil, the force on a single wire must be multiplied by the number of wires in the coil, N. Lab1: Finish Magnets and Magnetic fields . Experiment 8: Magnetic Fields and Forces Introduction In class you learned that a magnetic force F B is exerted on a charged particle as it moves through a magnetic eld B~. The magnetic field is a magnetic force that surrounds a magnetic object at all points in space. INTRODUCTION Magnetic flux most often denoted as Φm, is a measure of the amount of magnetic field passing through a given surface. Lab. Objective The objective of this lab is to measure the magnitude of Earth’s magnetic field in the lab. Introduction: The purpose of this lab was to use the magnetometer to find out the location, and also how far below the surface of the Earth a metal pipe is. 98 Experiment 18: Earth’s Magnetic Field Advance Reading Text: Magnetic field, vectors, right-hand rule for a wire loop, resistivity. 2: Magnets using . Magnetic fields can be defined as the regions surrounding a magnet where another magnet or a moving electric charge will feel a force of attraction or repulsion. Faraday’s Electromagnet Lab. where B is the magnetic field (in units of Tesla), I is the current, ℓ is the length of the wire, and θ is the angle between the current and the direction of the magnetic field. 7.2 Introduction Laboratory #6 Magnetic Fields Objective This experiment has 2 parts: (1) you will map the magnetic fields around a bar magnet and a current-carrying coil, and (2) you will measure induced currents using a bar magnet and a galvinometer. Magnetic Fields 7.1 Purpose Magnetic fields are intrinsically connected to electric currents. Do: read and do text problems, questions . The diagram above represents the magnetic field around a magnet. All magnets have magnetic fields around them, and it is this magnetic field, and the poles of the magnet, that are defining characteristics of all magnets. They are created by moving charges. Steady magnetic fields like those Procedure: Lay out a… Do: Magnets and Magnetic fields homework worksheet, concept questions from text .
