How rigt hand thumb rule is used in determining the direction of magnetic field around a conductor carrying current?
Curl the fingers of your right hand into the palm and extend the thumb. The thumb indicates the direction of the current, and the direction of the fingers indicates the direction of the magnetic field.
What shape do magnetic field lines have around a wire with a steady current in it?
a circle. using your right hand, if you point your thumb in the direction of the current, your fingers will curl around the wire in the shape of the magnetic field.
How do you compare and contrast the electrical field around a negative charge and the electric field around a positive charge?
Around a positive charge we have a repulsive field and around negative charge we have an attractive field.
How do you decide the 'Direction of Rotation' of a magnetic field?
There is a convenient rule called the "right hand grip rule":If you grip your right hand around the electric conductor with your thumb pointing in the direction the current is flowing, the magnetic field rotates in the direction your remaining fingers are pointing.See related Wikipedia link for an illustration.
What is the field surrounding every moving electron?
An electron is surrounded by an electric field. The electron is negatively charged. A moving electric charge creates a magnetic field. Use the "right-hand rule". Point your thumb up and curl your finger a bit so your hand looks like it is holding a bottle. If the electric charge (e.g. electron) is moving in the direction of your thumb, then the magnetic field it creates moves counter-clockwise in the direction of your fingers.
How rigt hand thumb rule is used in determining the direction of magnetic field around a conductor carrying current?
Curl the fingers of your right hand into the palm and extend the thumb. The thumb indicates the direction of the current, and the direction of the fingers indicates the direction of the magnetic field.
The playing surface of a football field is 120 yds long A player jogging around the perimeter of the field covers 346 yd How wide is the field?
53 yards
What shape do magnetic field lines have around a wire with a steady current in it?
a circle. using your right hand, if you point your thumb in the direction of the current, your fingers will curl around the wire in the shape of the magnetic field.
What are Waputica and Wapta icefields?
The Wapta Ice field is found in the Waputik Mountains. This ice field covers around 30 square miles in the Canadian Rockies.
Which law gives the direction of magnetic field due to a current carrying conductor?
The right hand rule. If you were to place your right hand around the conductor, with the thumb pointing in the direction of current flow, your fingers which are wrapped around the conductor will point in the direction of magnetic flux. Said another way, if you are looking at the end of the conductor and current is flowing towards you, then magnetic flux will be counter-clockwise.
What does area and perimeter of a figure refer to?
The perimeter of a field is how far it takes to walk around the edges. The area is how much land it covers. ■
What is an apposable thumb?
a movable thumb. like our them. its apposable because we can move it around and bend it.
What is thumb rule related to magnetic field and current?
THUMB RULE:If we put our one thumb in the direction of magnetic flux passes through the conductor,then the movement of the fingures denotes the direction of current flow.
What is the difference between a perimetre and area?
Perimeter = the distance around the edge of the field; how much fence it takes to enclose the field. Area = how much land-surface the field covers, i.e. how many corn-stalks can be planted on it. ================================= Perimeter: the distance around the edge of the floor in the room. Area: how much carpet it takes to cover the floor.
What does the expression thumb up your nose mean?
Doing nothing -- Standing around with your thumb up your nose.
What shape is magnetic field produced when current is passed through the wire?
it is called the thumb rule right hand curled means flux line thumb means direction of current. there will be a reversal of flux.
Which field manual covers various types of paramilitary organizations?
Field manual 7-100.3 covers various types of paramilitary organizations. The name of the manual is Opposing Force: Paramilitary and Nonmilitary Organizations and Tactics.
