  1. electromagnetism - How does the Earth's magnetic field protect it from ...

    Jul 12, 2019 · Earth's magnetic field, predominantly dipolar at its surface, is distorted further out by the solar wind. This is a stream of charged particles leaving the Sun's corona and accelerating to a …

  2. How are compasses influenced by a magnetic field?

    Apr 2, 2022 · More precisely saying, the compass needle will line up with the magnetic field lines produced by the bar magnet. These magnetic field lines come out from the north pole of the bar …

  3. magnetic fields - Is Earth's North pole actualy a South pole? - Physics ...

    Jan 9, 2021 · 0 As far as I am concerned, the compass is facing along the magnetic field lines on the Earth's surface which in turn points towards the North pole by its design. But for a magnet, the field …

  4. What is the effect of the Earth’s magnetic field on airplanes?

    First Lets consider take off/landing The blue lines are supposed to be magnetic field lines of earth, they are not normally so straight , but this would be a good approximation. Lets assume a $30^o$ angle …

  5. Even if molten iron in the interior of Earth is ionized & spins ...

    They keep saying that spinning molten iron generates Earth's magnetic field. But, even if that iron is somewhat ionized, those two lost electrons are still nearby in the fluid.

  6. Why does the Earth's magnetic field have an angle of 11.5°?

    Aug 14, 2023 · 7 Does anybody know why the magnetic field of the Earth have an angle of 11.5°? According to a theory by Prof. Blackett, Earth has magnetism due to the rotation of the the Earth …

  7. Why does the Earth not lose its magnetism? - Physics Stack Exchange

    Oct 22, 2018 · A magnet loses its magnetic properties when subjected to heat, the Earth's core is also hot but still it has magnetic properties, Why?

  8. Does the earth's magnetic field affect the sleeping position of a ...

    However the magnetic fields used in these studies are much, much stronger than Earth's magnetic field. No-one has ever shown that Earth's magnetic field has any effect on the brain, and you should feel …

  9. superconductor levitating in earth's magnetic field? [duplicate]

    The lift generated by magnetic field B on a superconductor of area S is: \begin {equation} F = \frac {B^2S} {2\mu_0} \end {equation} disregarding lateral forces and assuming superconducting cylinder …

  10. Why don't the Earth's oceans generate a magnetic field?

    Jun 16, 2021 · The earth's oceans do in fact generate a measurable magnetic field $^ { [1] [2]}$. As you have already pointed out, the motion of charged particles generate magnetic fields, so it makes …
