# Does Magnetic Field Depend On Length Of Wire?

The magnitude of the magnetic force also depends on the length of the wire in the magnetic field. The longer the wire in the magnetic field, the larger the force on the wire as shown in Figure.

## How does the magnetic field of a wire depend?

The strength of the magnetic field depends on the current I in the wire and r, the distance from the wire. The constant m 0 is the magnetic permiability.

## How does the magnitude of magnetic fields due to current?

Answer: Explanation: (a) a current-carrying straight conductor. (b) current carrying solenoid depends. So, magnetic field depends on the current flowing and distance (d) of that point. So, the magnetic field depends on the current flowing, the number of turns in solenoid and length of the solenoid.

## How do you find the direction of the magnetic field?

By pointing one's right thumb along the direction of the current, the direction of the magnetic field can by found by curving one's fingers around the wire. The strength of the magnetic field depends on the current Iin the wire and r, the distance from the wire. The constant m0is the magnetic permiability.

## What happens when current flows around a wire?

When current flows it creates a magnetic field. If you have a wire that is 5 cm with a single magnetic field loop, and you double it’s length, 10cm, you will have 2 magnetic field loops (around the wire) now.

#### Can You Climb Over Razor Wire?

Can you climb over razor wire? - The hardest way to climb over a barbed wire fence (apart from just grabbing the wire between the barbs and hoisting yourself up) is at an angle bracket. Angle brackets are used to keep the strands of wire at a 45 degree angle from the fence, making it harder for people on one side of the fence to climb over.

#### Why Does Solder Not Stick To Wire?

Soldering tip has oxidized (turned black) and solder won't stick to it. This happens when the tip is left bare while on--a naked tip will quickly oxidize at hot temperatures. The best advice for preventing this is to glob solder on the tip every time you set the iron down.

#### What Size Is Control Wire?

Yet control circuit conductor sizes of 14, 16 and 18 AWG are considered protected by a 20-A or less overcurrent device. And control circuit conductors of these sizes inside a control cabinet have even higher ampacities. No wonder some factory's electrical specifications require a minimum of 14 AWG wire.

#### What Do You Do With A Loose Ground Wire?

Yes, you can repair the ground wire by spicing the two pieces of wire together using a small twist on wire connector. Make sure the two ends of wire have the insulation removed about a half inch or more so the two pieces of wire may be joined together to complete the splice.

#### Why Does Wrapping A Coil Of Wire Around An Iron Bar Make It A Magnet When Current Runs Through The Wire?

By wrapping insulated wire around a piece of iron and then running electrical current through the wire, the iron becomes magnetized. This happens because a magnetic field is created around a wire when it has electrical current running through it. Creating a coil of wire concentrates the field.

#### How Far Can You Run A 30 Amp Wire?
