What is the direction of the magnetic field at the center of the coil?
The direction of magnetic field at the centre of circular coil is perpendicular to the place of the coil. i.e. along the axis of the coil.
How does the strength of the magnetic field depend on radius of the coil?
The strength of magnetic field depends upon: (i) Magnetic field(B) is inversely proportional to the radius of the coil. (ii) B is directly proportional to the number of turns n of the coil. For each circular turn, the direction of current is same.
What will happen to the magnetic field if the radius of the coil is increased?
Answer. 1) if the radius increases the magnetic field lines go farther and farther so the strength of the magnet decrease. So the strength of the magnet increase. 3) if the flowing in the circuit increases then the number of the magnetic field lines increased so strength of the magnet increase.
What will happen to the strength of the magnetic field if the radius of the coil is increased?
as we increase the radius of the coil , it’s magnetic field at the centre reduces . (b) Directly on the number of turns of wire in the coil. Answer: The magnetic field is inversely proportional to the radius of the coil.
How does the magnetic field strength at the center of a circular coil of a wire depends on a radius of the coil B number of turns of the coil?
The magnetic field strength varies directly with the number of turns of wire. It increases as the number of turns increases. Answer: The magnetic field at the centre of a circular coil of a wire is inversely proportional to the radius of the coil whereas Directly proportional to the number of turns of wire in the coil.
How does the strength of the magnetic field due to a current carrying coil change as its radius is decreased justify your response?
Answer. Biot Savrat Law affects the strength of magnetic field induced due to current flowing through the loop. Explanation: (1)When the loop’s radius is decreased as magnetic field strength formula is inversely proportional to radius of the loop, becomes double of the magnetic field strength.
What factors affect the strength of a magnetic field?
Factors Affecting the Strength of the Magnetic Field of an Electromagnet: Factors that affect the strength of electromagnets are the nature of the core material, strength of the current passing through the core, the number of turns of wire on the core and the shape and size of the core.
What are some harmful effects of electromagnets?
Reported symptoms include headaches, anxiety, suicide and depression, nausea, fatigue and loss of libido. To date, scientific evidence does not support a link between these symptoms and exposure to electromagnetic fields.
How do you protect yourself from the harmful effects of electromagnetic radiation?
These approaches involve reducing both the exposure level and duration.
- Disable Wireless Functions. Wireless devices — including routers, printers, tablets, and laptops — all emit a Wi-Fi signal.
- Replace Wireless With Wired Devices.
- Keep EMF Sources at a Distance.
- Use Your Smartphone Safely.
- Prioritize Sleeping Areas.
Does WiFi mess with your brain?
Excessive WiFi exposure is known to be associated with disrupted learning and memory, sleep deprivation, and fatigue related to reduced melatonin secretion and increased norepinephrine secretion at night. However, the use of any screen time is also associated with these changes.
