Zero O d. 5.5x10-10Jnillan Learning Activity on the Sun, such as solar flares and coronal mass ejections, hurls large numbers of charged particles into space. When the particles reach Earth, they can interfere with communications and the power grid by causing electromagnetic induction. For example, a current of millions of amps (known as the auroral electrojet) that runs approximately 100 km above Earth's surface can be perturbed. The change in the current causes a change in the magnetic field it produces at Earth's surface, which induces an emf along Earth's surface and in the power grid (which is grounded). Induced electric fields as high as 6.0 V/km have been measured. We can model the circuit at Earth's surface as a rectangular loop made up of the power lines completed by a path through the ground beneath. We can treat the magnetic field created by the electrojet as being uniform (but not constant) and parallel to Earth's surface near the surface. Consider a 1.0-km-long stretch of power line that is…
- Keeping in mind that the magnetic permittivity of free space is μ0=12.56x10-7 T.m/A, how strong magnetic field you measure in the lab when 25 A current is applied to a coil with 400 turns/meter.A singly-ionized methane atom (mass of 2.66×10-26 kg) follows the dotted path shown when sent into a mass spectrometer with a uniform magnetic field. Assume that the magnetic field in the mass spectrometer is caused by a large solenoid with a radius 54 cm, that is 0.6 m long and made up of 5900 loops. If a 9 T magnetic field is needed to detect a certain compound, how much current needs to be run through the coils of the solenoid? 7.28×102 A 6.56×102 A 1.21×103 A 2.43×107 A 1.11×103 A-25 1.58 x 10 A phosphate molecule PO of mass m = difference |AV| = 4.35 V and enters the mass spectrometer with magnetic field of magnitude |B| = 0.090 T. The particle then follows a semi-circular path shown in the picture before kg is accelerated across the potential reaching the detector located to the left of its entry point. В d Δν a) Sketch the described situation (you can start with the figure shown in the problem) CLEARLY indicating the direction of the magnetic field inside the mass spectrometer b) Determine the speed of the particle as it enters the region of magnetic field. c) Determine the distance between the entry point of the particle and the detector.
- Suppose that you apply +3.0 ± 0.1 A through a solenoid that has 100 ± 0 turns perunit length and a core with a magnetic permeability of 5 x10 –5 ± 0 Tm/A. What isthe value and uncertainty of the resulting magnetic field? plz hurry. tnx3) Recall that we can analyze the nature of particles with a velocity selector and mass spectrometer. Suppose we know that the charge of the particle we're experimenting with is that of an electron but we don't know their speed and we don't know their mass. a) The velocity selector is constructed to have a magnetic field of 0.157 pointing into the paper plane and an electric field of 70N/C pointing downward. What is the speed of negatively charged particles if they don't experience any deflection? b) Suppose that those particles that are not deflected then enter a magnetic field of 37 pointing into the plane (no electric field). If we measure a diameter of the circular orbit in this magnet field of 1cm what is the mass of the particle?1. Take e/m to be the accepted value of 1.76-10¹¹ C/kg. For a plate voltage of 100 volts and a circular beam of radius 3.0 cm, what would you expect the required magnetic field B to be? Assume that the above magnetic field is produced by two Helmholtz coils, and assume that each coil has 119 turns, a radius of 106 mm, and a separation of 106 mm. What cur- rent I is required to achieve the expected magnetic field?
