What does a weak magnetic field suggest?
What does a weak magnetic field suggest?
A weaker magnetic field will make the planet more susceptible to solar radiation and put space equipment at risk.
What is strong and weak magnetic field?
The density of the lines indicates the magnitude of the magnetic field. At the poles of a magnet, for example, where the magnetic field is strong, the field lines are crowded together, or more dense. Farther away, where the magnetic field is weak, they fan out, becoming less dense.
What is the weakest magnetic force?
0.5 femtotesla/√Hz
The weakest magnetic field measured is 0.5 femtotesla/√Hz, and was achieved by Dr. Sheraz Khan (Pakistan) and Dr. David Cohen (USA), at the Martinos Center, Massachusetts General Hospital, Charlestown, Massachusetts, USA, and was published in the Review of Scientific Instruments on 1 May 2013.
How can you tell if a magnetic field is stronger or weaker?
The magnetic field magnitude is proportional to the density of the lines. The closer together the field lines, the stronger the magnetic field. The more spread out they are, the weaker the magnetic field.
Where is the magnetic field the weakest?
Intensity: The magnetic field also varies in strength over the earth’s surface. It is strongest at the poles and weakest at the equator.
Why is Mars magnetic field so weak?
Early Mars boasted an Earth-like magnetic field that shielded it from solar radiation and helped the planet hold onto its atmosphere. But as the Martian crust cooled, its magnetic field weakened. Now, new research reveals that this scrawny magnetic field may have been worse than no field at all.
What is a strong magnetic field?
Magnetic fields that surpass about a billion Gauss are so strong that they compress atoms to tiny needles, destroying the ordinary chemical bonds that bind atoms into molecules, and making chemistry as we know it impossible.
Where is the magnetic field weakest?
Which of the following has weakest magnetic field?
The magnetic field varies in strength over the earth’s surface. The Earth’s magnetic field is weakest at the equator and strongest at the poles….

What determines strength of magnetic field?
Answer and Explanation: The strength of a magnetic field is determined partly by the distance from the field source and by the initial strength of the magnet itself.
Where is the magnetic field strongest and weakest in solenoid?
The magnetic field is weakest at the center and strongest between the two poles just outside the bar magnet.
Which of the following has the strongest magnetic field?
Out of the Earth, the Sun, Jupiter, and a pulsar, a PULSAR has the strongest magnetic field.
What happens if a planet has a weak magnetic field?
With simulations, Seki, study lead Ryoya Sakata (also at University of Tokyo), and their colleagues show that a planet with a weak magnetic field would lose ionized oxygen and carbon dioxide from its atmosphere 100 times faster than one with a strong field — and six times faster than a planet with no magnetic …
Can Earth lose its magnetic field?
Scientists don’t know what drives pole reversal frequency, but it may be due to convection processes in Earth’s mantle. During a pole reversal, the magnetic field weakens, but it doesn’t completely disappear.
Which magnetic field is the strongest?
Scientists Just Generated the World’s Strongest High-Temperature Magnetic Field
- A new high-temperature superconducting magnet has reached 20 teslas.
- The magnet is as powerful as a previous structure 40 times its size.
- The added power (with reduced bulk) could help enable nuclear fusion.
Where magnetic field is the strongest?
The magnetic field is strongest near the poles of the magnet. It is equally strong at both the poles. The magnetic field lines are closer near the poles. The strength of the magnetic field depends on how close the magnetic field lines are.
Where is the magnetic field the weakest in a solenoid?
the center
The magnetic field is weakest at the center and strongest between the two poles just outside the bar magnet.
What is the strongest magnetic field?
The Insight-HXMT team has performed extensive observations of the accreting X-ray pulsar GRO J1008-57 and has discovered a magnetic field of ~1 billion Tesla on the surface of the neutron star. This is the strongest magnetic field conclusively detected in the universe.
What is the value of K in magnetic field?
Unsourced material may be challenged and removed. The Coulomb constant, the electric force constant, or the electrostatic constant (denoted ke, k or K) is a proportionality constant in electrostatics equations. In SI units it is equal to 8.9875517923(14)×109 kg⋅m3⋅s−2⋅C−2.
