"Hall's Discovery Comparable with the greatest ever made by Michael Faraday"--Kelvin Edwin Hall. "On a New Action of the Magnet on Electric Currents" being an offprint from the American Journal of Mathematics. 2 (3): 287 292, 1879. Original wrappers. This offprint has seen its fair share of bumps and bruises probably a little too tall (12.5") to be in wrappers this thin. FAIR copy, only. [++] "The Hall effect, development of a transverse electric field in a solid material when it carries an electric current and is placed in a magnetic field that is perpendicular to the current. This phenomenon was discovered in 1879 by the U.S. physicist Edwin Herbert Hall. The electric field, or Hall field, is a result of the force that the magnetic field exerts on the moving positive or negative particles that constitute the electric current. Whether the current is a movement of positive particles, negative particles in the opposite direction, or a mixture of the two, a perpendicular magnetic field displaces the moving electric charges in the same direction sideways at right angles to both the magnetic field and the direction of current flow. The accumulation of charge on one side of the conductor leaves the other side oppositely charged and produces a difference of potential. An appropriate meter may detect this difference as a positive or negative voltage. The sign of this Hall voltage determines whether positive or negative charges are carrying the current."--Encyclopedia Britannica "The Hall effect is the production of a potential difference (the Hall voltage) across an electrical conductor that is transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879." Wikipedia [++] "Hall is best known for the effect bearing his name; it formed the basis of his Ph.D. dissertation and was the subject of many of his later researches. He was stimulated by Rowland to question a statement in Maxwell s Electricity and Magnetism that the force acting on a conductor in a magnetic field acts on the conductor directly and not on the electric current. Hall s experimental persistence was rewarded when he found that a current through a gold conductor in a magnetic field produced an electric potential perpendicular to both the current and the field. The notion that this was due to simple interaction between the current and the field had to be abandoned, however, when other metals were found for which the effect was in a direction opposite to that predicted. Hall s discovery was termed by Kelvin as comparable with the greatest ever made by Michael Faraday. It sparked interest in studies in this area, and three other transverse effects were soon discovered; they bear the names of Andreas von Ettingshausen, Walther Nernst, and Augusto Righi and Sylvestre Leduc."--Complete DSB online.…

Terms of sale
All items are offered with a seven-day return privilege.
Right of withdrawal
If you are a consumer you can withdraw from the contract in accordance with the following. Consumer means any natural person who is acting for purposes which are outside his trade, business, craft or profession.
Information regarding the right of withdrawal
Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.
The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.
To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.
You shall send back the goods or hand them over to JF Ptak Science Books, Hendersonville, North Carolina, U.S.A., without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.
Exceptions to the right of withdrawal
The right of withdrawal does not apply to:
- The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
- The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.
